The reason why the case can attract people's interest is that it is widespread. lies in its unknown. But the difficulty of the first is also that it is unknown. The temporary investigation team has been in this mysterious unknown for more than ten days, and the remaining leaks have been exhausted one by one."

The first seven groups were nothing though. A lot of work has also been done in the investigation and investigation, especially at that time, Guo Dingshan's group once found a suspected eyewitness in the shop at the entrance of the community at that time, confirming that Zeng Guowei left by car. However, it was not accepted. Because the witnesses themselves are notoriously alcoholic in the community, and that is the current generation. There are tens of thousands of people running on the streets of Tianjin, which is hailed as "locusts" by the masses, and there are no license plates and car numbers as evidence, how can they be checked? However, this detail faintly corroborates Jian Fan's inference, and was knocked out by Shi Jihong, and when Guo Yuanxing rushed down to investigate, it was found that even the suspected eyewitness had already died.

For more than ten years, not only people have changed greatly. Those who dare to die are gone.

Zhang Jie wants to say that he is also a good hand at investigating the case, according to the template given by Jian Fan, the focus is not to come out with more than 20 people who have a history of reselling cultural relics and violent injuries A few times, either too old or too old, about the same age. Another denial case was not in Dayuan at all, and when a few more suspects were found, the other party gave the most powerful proof, the case was in 199. They are still serving their sentences in prison. You can't break out of prison and commit crimes, can you?

Evidence-based. These people still dare to straighten their necks and refuse to admit it, not to mention that you asked about it more than ten years ago. I know I won't tell you.

Day after day passed, and there was no progress at all, which is difficult. Those who have not experienced it can't figure out the hardships, and a group of people are like donkeys pushing horses that are grinding, and they circle around this unknown countless times. Circle. The files were turned over and over again, and the suspects were implemented one by one, and the clues of negation and negation were chaotic. Impatience and uneasiness have already been secretly born in the temporary investigation team, and if it weren't for the temporary team leader getting together every once in a while, eating and drinking to entertain them, it would really be difficult to bring people's hearts together.

Jian Fan is quite back this time, this team leader should be the well team members to carry it, there is no clue at all, from Xiao Chenggang's complaining words, the team members can hear it, these days in the Nangong antique market wandering. Still didn't do the.

Today, he was still wandering around the market, counting his fingers for more than two weeks, and seeing that there were only five days left before the deadline set by Deputy Director Xiao, Jian Fan's heart was a little impatient. This case is far more difficult than imagined, and the clues from this copy of the city bureau are not in it, regardless of whether the suspect is in it or not. It is difficult to investigate those suspects alone, some are still serving their sentences, some do not know their whereabouts after serving their sentences, and even if they know their whereabouts, there are those who cannot be found. More than a dozen people have carefully checked the traces of dozens of people, but they still found nothing. Now the cognition of this group can be regarded as an extra layer, and this group of talents is really home and home from all over the world. It's not that easy to find a specific person.

Teammate Xiao Chenggang was too lazy to accompany Brother Guo anymore, talking nonsense from stall to stall, sitting far away on the edge of the market and eating cold noodles. There is another person by Jian Fan's side, who is the administrator of the Nangong antique market, surnamed Yao, a typical official who is a good place, and he is a native of Dayuan. While accompanying Jian Fan, he introduced: "This market has been built for nineteen and a half years. I've been working here for 20 years, "At that time, there were three or five people who shopped seven or eight stalls, you look at the scene, the hairy people don't know where they came, but how much, on Saturdays and Sundays, there are also Beijing, Tianjin to buy goods, there are so many antiques, this group of hairy people, don't you look at all the countrymen, thieves are very good? Get a broken tin bottle and throw it in the pit for a year and a half, and when you come out, you dare to say that it is from the Song Dynasty; if you get a broken book, you will dare to say that it is the goods of the Qing Dynasty; there are even more powerful ones. Look at that bald hair, that eagle hooked nose, don't see through it, you can't beat it with 100,000 yuan, this old guy can make more than 30 kinds of copper coins, I have been doing it for 20 years, and people have been selling it for 16 years, and I haven't seen him sell it once, really, fuck. Do you say that people have lost their minds and gone crazy these days, and exchanged real money for fake money"

As an outsider, maybe you can see the industry more clearly, Administrator Yao chattered.

Jian Fan smiled and followed Administrator Yao's fingers to see that it was an old man in his forties and fifties, wearing a dirty coat and a pile of dirty copper coins on the stall. There is a group of bargaining around, and it seems that they are all taking advantage of the cheap leakage, but perhaps as Administrator Yao said, it is estimated that there is no genuine goods there, and there are genuine people who will not take them out to sell them. Listening to Administrator Yao's nagging, Jian Fan smiled and asked the topic: "Uncle Yao, I have turned around all the stalls in the shops here, you helped me find the one with the longest age and the most intelligent ears, don't you also have an impression of Zeng Guowei? Zeng Guowei's hobby is ancient coins, ancient books and other antiques, there are not a few people in this market I want to know him, so bald Cheng? ”

Administrator Yao smiled, and when the two of them were about to walk to the stall, the administrator came down, staring at a certain stall with slanted eyes, Jian Fan saw that he had also been to the stall by himself, and the stall owner was an old man in a gray coat. The beard is white, quite a bit of dust, every day sitting cross-legged in a corner of the market with his eyes closed, in front of him are stacked high and low books, from the Song and Yuan dynasties to the Ming and Qing dynasties, there are basically. Yao Guan turned around and clapped his hands: "It's not okay to be bald, look for him, white hair." ”

"White hair?" Jian Fan was happy when he saw that, this nickname was so vivid.

"Haha" This beard, longer than the years I have been there, when I met him, he was still half black and half white, people called him miscellaneous hair, but now it is all white. It's simply called Bai Mao, and his surname is Bai, I heard that his ancestors also did this business before liberation, and he was still a rich family, but when it came to his generation, he was so good "Don't be bluffed by this look, this old guy has a hand in making fake books, I suspect that this beard may also be fake, and it is so white." Maybe it's the same as the yellow head of the girls now. Dyed haha..."

Administrator Yao said, leading Jian Fan to fight, Jian Fan just squatted down and looked at the bookstall with interest, the old man's eyes opened and chirped: "A book of thirty, the price of words is not two" Look at this, the little brother is full of heaven, and the fourth of the pavilion must be a rich and noble Lan person, how about the old man send you a word? .

"What words?" Jian Fan asked in a stunned voice.

"Don't listen to him. Administrator Yao shouted: "Buy him a book in one sentence, this old guy can't sell books, so he has this bad idea" Hey Baimao, you even slaughtered the police? Don't trouble me. ”

Jian Fan was amused by the words of the two, daring to love is also the truth of the rivers and lakes, and his mouth is not empty. With a smile, the old man Bai was not happy, glanced at Administrator Yao, and scolded angrily: "Fat Yao, I didn't pay less management fees, so there is such a disturbing business?"

One sentence is a bit exposed, it is obviously a bickering between the market masters, and it looks like the fairy wind bones do not eat the fireworks in the world just now. Jian Fan was so amused that he smirked, in the midst of all kinds of things in the market. There are a lot of daring and fun. It's all there.

Administrator Yao introduced that this was the criminal police of the Municipal Bureau, and he wanted to understand the situation and introduce them to each other, but Jian Fan's eyes were not friendly to the old man, especially to Administrator Yao. Hurriedly persuaded Yao Guan to leave, turned around and respectfully called Uncle Bai, handed Zeng Guowei's photo to Old Man Bai, and asked, "Uncle, do you know this person?"

"Yes, you guys, why do you come to ask me?" the old man pouted without being salty.

Jian Fan Yile put away the photo and asked excitedly: "Then uncle, have you seen him all these years?"

Shake one’s head.

"Do you know anything about him?"

Shake one’s head.

"When was the last time you saw him?"

Still shaking his head.

Shaking his head after asking three questions, it seems that the old man's indifference to Yao management has been inherited to himself, Jian Fan thought about it, his eyes and bones turned, the business of this bookstall is not very good, a bunch of ancient books are still musty under the careful smell, I really don't know how to sell this thing, look at the old man pretending to close his eyes and recuperate, Jian Fan smiled and said: "Uncle, in fact, you don't know, I am a lover of ancient books" I have a lot of this kind of ancient books stored at home, can we do this?" Old rules, I'll ask you a few questions, one question buy your book, "How about it?"

Yes, nodding. Jian Fan smiled secretly. He first took a copy in his hand and asked, "Uncle, I heard that you have the most information in this line and have done it for the longest time, and you are in this line." In the past ten years, has there been a windfall overnight?"

"Yes" the stalls are all taking care of food and clothing to save a little money, and the shops in front of you are all windfalls. The old man said casually.

Jian Fan looked up, a street has been around for more than ten days is already very familiar, operating calligraphy and painting antiques Wuyue Pavilion, operating pottery Agarwood Xuan, operating jade Jubao Zhai, and operating miscellaneous Bo Lian Pavilion There are a lot of large and small plaques hanging on a street, only to save it at a glance, this book was bought in vain, the first question is equal to not asking, they are all rich masters.

"I'm asking the kind of lord who gets rich overnight and has a big windfall. Jian Fan explained, looking at the old man as if he was asking.

The old man smiled in surprise, saw that Jian Fan had forgotten to take the book, took the book and put it in front of Jian Fan, and said with a smile: "If you want to get rich in this industry, you will get rich overnight, and you will get rich overnight, and you will have a windfall, all of them are relatively large, how many there are, that is unknown, he doesn't say that you will never know." ”

Yes, I bought two copies, and I asked in vain. Jian Fan's mind turned, and he said again: "Uncle, who can count the ruthless master in this industry?"

"That's a good question. In this industry, those who have no heart and white hands are black enough. The bigger the business, the darker it gets. ”

"If anyone kills people and sets fires, does anyone dare to do it? For example, to rob a priceless antique?"

"Dare, all dare, I dare. ”

"Who has Qin Yang's thugs, for example, have you seen or heard of something similar?"

"Yes, both. The police can cover half of the sky, and the remaining half will be solved on their own. Doing business depends on mouths, and robbing business depends on fists. ”

"Do you know about the case of smuggling antiquities fourteen years ago? It seems that three of those four people came from this market.

"Yes. But you should know better than I know."

As he spoke, inadvertently, the agreement of a sentence and a book had already thrown a large handful of books in front of Jian Fan, and when Jian Fan could stop talking, there were already more than a dozen books on his lap, and after asking for a long time, he still talked back and forth, counted dozens of four, raised his eyes, and the old man looked at himself with a smile, like looking at a deceived little baby. Jian Fan couldn't ask anything when he looked at it, so he counted the money stupidly and handed it over: "Uncle, fourteen books, four hundred and two, you order." ”

A trace of surprise flashed in the old man's eyes, and he didn't answer, Jian Fan smiled and persuaded: "Uncle, it takes up your time, I know a lot of information, you get paid for your work, you're welcome." ”

Only then did the old man take it and stuff it into his pocket at will. commented: "Little brother, you are a novice at first glance." ”

"Really? Jian Fan said with a smile.

"There is no hostility in his eyes, he speaks very politely, his face is upright, and he is a kind person" I won't tell you, I have seen two good policemen, one is you and the other is Zeng Guowei. The old man commented and gave Jian Fan a good evaluation, eighty percent of which was because he received the money. As soon as Jian Fan heard this, he went downhill, put a thick handful of ancient books back on the old man's stall, and said as if asking, "Uncle." That's good, I'll use this fragment of the book worth 402 yuan, and exchange it for a few more words? I can't even recognize all the words on it, so it's better to keep it than to change a few words to you. ”

"Say" to send you a few words for free. ”

"Tell me about another good cop. You know. ”

Jian Fan was so polite that he gave the book to the old man as a talking point, and four hundred and two was equal to nothing. The old man accepted it. Frankly said: "Oh,, Xiao Zeng, hehe, he is a good person" When I came to Dayuan to eat, I was robbed of half of the stall by the gangsters on the first day, or Xiao Zeng helped, and it has been twenty years in a blink of an eye" Xiao Zeng's family history is very good at distinguishing ancient books in the Song, Yuan, Ming and Qing dynasties. Paper, thread, ink, and paste can be seen at a glance, I also learned a three-legged cat kung fu at that time, and I was shocked to see him. He has a nickname called Zeng Sanyan, that is, he has a third eye, others can't understand, can't understand things, he can see, but all the ancient coins and ancient books that have an unstable idea, you have to ask Zeng to pass the eyes of the law, the oldest Bo Bange Pavilion in the store He is a frequent customer, and several want to invite Xiao Zeng to sit in the store. But Xiao Zeng, I can't say it, I don't want to come out if I guard the Chenhu bowl"... It's a pity, I haven't seen him for more than ten years... It seems that I heard that he got some kind of treasure, and his family moved away, "If this market had been in Xiaozeng, he would have become a multimillionaire for 20 years."

The old man seemed to have looked down on life, and said slowly and calmly, but most of the words were related to the antique industry, and most of these things Jian Fan didn't understand. When the old man's words were about to come to an end, Jian Fan looked at Xiao Chenggang in the crowd and rushed up in a panic, feeling that something was wrong, he hurriedly said goodbye to the old man, and was pulled away by Xiao Chenggang who ran up together, and said as he walked: "Hurry up, Brother Guo, Zhang Jie has a huge appearance, I want to report to the team leader."

What's what's now" is still huge, you don't know how to use words. ”

"He said he was a suspect. He told you to hurry back to the team.

"I'm just Zhang Jie's IQ?"

"I don't believe it, he has a bunch of punishments on his head, all of which were done by the wrong person. ”

"Let's go back first..."

Whether to continue to recover from the mountains and rivers, or to come to a bright future. Jian Fan can't say for sure, it's already the twenty-fifth when he calculates, and then think about Zhang Jie, who is usually more stubborn than himself. Jian Fan really couldn't believe that this guy had done something decent, Xiao Chenggang and Jian Fan hurriedly got into the police car, and roared all the way to the detachment......

The fourth volume is full of songs on all sides, chapter 1, the mountain people don't know how to let it,

Pushing the door in, the people in the office were startled, and Xiao Chenggang and Jian Fan, who entered the door, were also startled. People are all. Shi Jihong, Yan Shijie, Guo Yuanhe, and Zhang Jie, who was standing in the position of the temporary team leader and pasting a few photos, were discussing something, and Jian Fan, who entered the door, asked in surprise: "What's the matter?"

Guo Yuan pointed at Zhang Jie and looked back at Zhang Jie, but he saw that he was thin and capable. Jian Fan and Xiao Chenggang sat down suspiciously, looked at the photos, and asked strangely: "Zhang Jie, aren't there a few suspects who have been arrested in the 3 Fei cultural relics smuggling case? It can't be related to them anymore, right? They were in the detention center at the time, right?"

"Hey, hey"... I don't know if it's them, but my current is the biggest appearance in the Dayuan police world this century, do you want to hear it?" Zhang Jie said with a babbled expression. Jian Fan looked at the few people present, they all seemed to be smiling, and he dared to be in the dark with Xiao Chenggang, and nodded stupidly.

"Good basic facts. In 199, after the investigation of the five-month major case in 3 Fei, the four suspects Qi Shumin, Li Sanzhu, Chen Jiuwen and Zheng Bensheng were sentenced to 20 years and 15 years respectively. , I also learn from our temporary team leader. Pick a big case, haha"

Zhang Jie stood in the center of the office. Counting the four suspects, the door was not closed, so he hurriedly stepped forward to close the door, locked it, watched everyone smile, and said it as if the temporary team leader was standing in the center a few days ago.

"Let me first talk about the whereabouts of these people, Qi Shumin, who was sentenced to 20 years in prison for reselling cultural relics, and after serving six years and eight months in prison in the Northwest Labor Reform Farm, he was released on medical parole for physical reasons Chinese. I actually have a foreign nationality and become a citizen of St. Kitts. ”

Zhang Jie stunned Xiao Chenggang and said: "Chicken wings!? What are you talking about, what about pork knuckle." ”

"That's right, what kind of place is this, haven't you heard of it?" Jian Fan was also confused.

Yan Shijie explained with a smile: "The small island of Central America, which is known as the paradise of the rich, can apply for citizenship as long as you sell a villa worth $700,000. Moreover, taxes are relaxed there, and passports are exempt from inspection in more than 70 countries in the world. Now it is the place of choice for the wealthy to emigrate. ”

It dawned on me. Became rich. Jian Fan took a closer look at the photos, more than ten years ago, like a high-spirited and promising person, when he heard Zhang Jie's introduction, he was suspicious, 20 years in prison, less than half of the sentence, parole, immigration... What exactly does Zhang Jie have to say?

"Okay, the first to become a rich man, let's not talk about it for the time being" The second person, Zheng Bensheng, was sentenced to a year in prison and was released after serving eight years and six months, but four years ago he recommitted the crime, and he was still reselling cultural relics, this case was Hu Lijun was responsible, she still remembered that this person was arrested from Jiangsu, and the second crime was sentenced to death with a reprieve, and the sentence was commuted to life two years later. He is currently serving his sentence at the Fenyang Labor Reform Farm. Zhang Jie pointed to the photo and explained, this is a beard, and he looks very fierce.

Dogs can't change their eating. Hehe," Shi Jihong commented with a smile.

"Three people, Chen Jiuwen, served six years in prison, and after returning to Dayuan, it is said that they have a good life, and they also bought a house in Xingyuan Community. However, this person is relatively back, and he died in a car accident three years ago, "The fourth Li Sanzhu, this one is even more strange, and there is no trace of it." Tell me, isn't it strange?" Zhang Jie introduced in a few sentences. Look at the crowd.

Jian Fan heard it in a fog. Dare to call himself back just for such a. said angrily: "Zhang Jie, you eat pork and eat it like a pig's head, what a fart are you talking about? Wealthy, what does it have to do with our case?"

This sentence is deliberately doubting, look at how deep Zhang Jie's current situation is, in fact, these four people are judged to be not simple from these characteristics, Jian Fan said this, under normal circumstances, Zhang Jie must be speechless to play tricks, but today is evil, Zhang Jie smiled or calmly, and said playfully: "Temporary team leader, I haven't finished yet?"

"That's not a quick thing to say. Jian Fan said.

"Hehe" I'll tell you a few things, and you'll find it interesting. First things first. Qi Shumin has a brother, named Qi Yuanmin, Nangong Antique Market has opened a shop that deals in antiques, called Wuyue Pavilion, you should have seen the team leader, right?

Zhang Jie said this, Jian Fan's eyes widened and he was stunned. It's really a bit of a dare to be affectionate, interesting. I suddenly recalled what the white-haired old man said, the biggest one was the blackest, did the Foggy Moon Pavilion have something to do with these brothers.

"The Foggy Moon Pavilion was settled in Ohara three years after the 3 Flying Case. Prior to this, Qi Yuanmin was also an unemployed vagrant in Cloud City, and at that time, millions of dollars were invested. Is there a problem with the source of this money? It has something to do with the few people who live in his prison, Han?" Also, several people have received significant commutations in their sentences, let's talk to our own people behind closed doors, the expenses here are indispensable, right?

Jian Fan was stunned, looking at everyone, in the past twenty days, there were so many things under his nose in a daze, and he was really a little stunned. However, I was even more surprised that Zhang Jie didn't see him overnight, as if he had changed as a person, speaking clearly and hierarchically, and focusing all the doubts on the Qi brothers little by little.

"The second suspicion, after Chen Jiuwen was released from prison, he has been working as a driver for Qi Yuanmin, according to the on-site investigation of the third squadron of the traffic police, the perpetrator should have deliberately crashed into Chen Jiuwen's car, but there is no follow-up. ”

"The third suspicion, Zheng Bensheng's case of smuggling cultural relics, faintly points to Qi Yuanmin. Hu Lijun once conducted routine questioning of Qi Yuanmin, but this old guy didn't admit anything, and the serious crime team had no evidence to accuse him. You can only release people. ”

"Fourth, suspicious, although Qi Shumin has foreign nationality, he has several entry and exit records every year, that is to say, he is going back and forth internationally, and what he is doing in China. Whether it is still hiding in Ohara or not, it is unknown. ”

"The fifth suspicion. Wuyue Pavilion has been used for less than ten years, and it is one of the best antique shops in Dayuan" Two years ago, an ink painting of Bada Shanren set a record of 3.8 million yuan at auction, and it is very famous, and it has faintly become a leader in the industry. Haha: "It's a family history." ”

Zhang Jie said eloquently, Jian Fan was dripping with cold sweat, and dared to love that the first day he entered was Wuyue Pavilion, and he was stupid He took Zeng Guowei's photo and asked the smiling boss, and the boss politely said that he knew. He also has a business card on his body to help the people.

Damn, what's this called, dare to be affectionate...... Dare is around. Jian Ji secretly drummed in his heart, a little unsettled. Xiao Chenggang sighed, looked at Zhang Jie with surprise and envy, and gave a thumbs up: "Wow" touched the big fish. ”

Zhang Jie Jian Fan thought for a long time and looked at everyone looking at him with concern, and then said: "This is still speculation, you just gave me a big suspicion, the suspicion is very serious, but there is nothing that can explain the problem." You mean, after Qi Shumin was arrested, his brother Qi Yuanmin organized forces to carry out the theft of the Jinyuan Branch, right? But in this case, who is the specific perpetrator, even if it is under Qi Yuanmin. That must also be Xuezang, who can't see the light, "Have you checked this?"

"Checked. ”

Zhang Jie said again, which startled Jian Fan, as if he hadn't seen him for several autumns, Zhang Jie had become so smart.

Seeing that this little policeman who suddenly became smarter explained confidently: "Qi Yuanmin has a thorn named Xue Jianting under his subordinates, who has a history of injury, and the Liuxiang Police Station has arrested him, and the Nangong Police Station has also detained him several times. He's got to get his hands on it. According to the Liu Gong Police Station, this kid is a bit perverted, and his whole body is tattooed with nude women, and others call him "Huating,... , Team leader, speaking of which, I have to admire you, your old man's eyes are black, and without any clues, your screening template actually screened out Xue Jianting, and he is among the islanders... I'll show you his detailed file. ”

Hiss...", Jian Fan gasped, stunned by this huge appearance, and stroked his stomach with a gesture, it was difficult to do it. Dig up a big fish again?

At the time of the file, it was the file of the police station, and he was sentenced to criminal detention for the crime of assault, and the person in the photo had a shaved head and eyes like angry eyes. With a high nose and wide lips hanging from the horizontal meat, the typical animal look, and the tattoos attached to the neck can be faintly seen. Jian Fan was flustered in his heart, looked nervously, looked at Shi Jihong and Yan Shijie without a heart, and then looked at a few teammates, and asked weakly: "Then what should we do?"

Everyone laughed sneered, and Zhang Jie said as if he hated iron: "Team leader, you are also the team leader temporarily?,... It's up to you now? It's been more than 20 days. It took me hundreds of years to dig up this line. Hey, you have to think it's worthless, I'm not bored. ”

"Don't, don't talk about that, it's very valuable. I met Qi Yuanmin in Nangong, and he knew Zeng Guowei. Jiang Fan said stupidly.

"Huh!?" was another piece of surprising news.

Xiaofan, I suggest a sentence. Yan Shijie also became serious when he heard it, and Zhengse reminded: "Just a few people in the office now, you have to emphasize confidentiality." Whether it is or not, no matter how you check it, it must be carried out in a state of secrecy, otherwise it will be full of wind and rain as soon as it comes out. According to the results of Zhang Jie's investigation just now, this is not a simple person, he has been in business for more than ten years and has been deeply rooted, who dares to guarantee that it will not reach people's ears. ”

Everyone listened to the old man's words. Yes. Shi Jihong praised Lao Yan for being thoughtful, and when he turned around, he asked Jian Fan about his next step, Jian Fan thought for a while, and gritted his teeth: "Check, Zhang Jie." You and Guo Yuan look down to see what else is there. Xiao Chenggang. Come with me and apply for an external transfer. ”

"Where are you going?"

"Fenyang. ”

Hey, Brother Guo, it's almost time to get off work, more than 200 kilometers?"

"Two thousand kilometers are also abandoned. ”

There are really clues, and everyone's hearts were brought up in an instant, only Xiao Chenggang was not very happy, and the two of them were just about to leave, but Shi Jihong also grabbed it: "I'll go too." ”

"Don't"... Aunt Shi, you are so old, and you have traveled so far. Jian Fan said soothingly.

"Let her go, her mother's house is in Fanyang, maybe there is an acquaintance to take care of it, not to mention that she was born as a pre-trial clerk in the old days, and she is better at interrogating people than you. Yan Shijie saw through Shi Jihong's intentions at a glance.

There is no need to think about this, Guo Yuan and Zhang Jie seem to have broken through at the same time, and happily double-fived, wanting to go back to the serious case team to read the information of Qi Yuanmin. Jian Fan, Xiao Chenggang and Shi Jihong came down in a hurry, Jian Fan personally drove the car, went back to the first team to make a letter of introduction, and drove straight out of Dayuan"
