"Nephew to see aunt!" The pink little handsome guy Li Chengdao bowed down and saluted Princess Pingyang. Pen × fun × Pavilion www. ｂｉｑｕｇｅ。 ｉｎｆｏ

"Dao'er, why are you free today?" Princess Pingyang was also quite surprised at this time and came over to help him up, since the last birthday banquet, she also saw Li Chengdao for the first time, and she knew that Li Chengdao usually had a heavy homework and almost no time to go out, so when she heard that he came to visit her, she was also very surprised.

"It's a coincidence, these days Wang Fu took me out to observe the river situation near Chang'an, just today to observe the Yellow Canal, my nephew finished his homework and proposed to Wang Fu to visit his aunt, Wang Fu also agreed!" Li Chengdao also replied with a smile at this time.

Don't think that the daily education of the princes and grandchildren is to die and study, in fact, the ancient elite education they received is very comprehensive, which is more similar to the quality education of later generations, especially people like Li Chengdao who are likely to inherit the throne in the future, in addition to reading, they must also understand astronomy, geography, military and other knowledge, otherwise how to be a good emperor?

"It turns out that you have already started to study geography, but do you have any experience?" Princess Pingyang was also very concerned about Li Chengdao's studies, and asked with a smile.

"There are some experiences, but there are also many questions, and even a few princes can't answer them." Li Chengdao obediently replied that he is a child who likes to think independently, and after learning a lot from the teacher, he will also add his own thinking, but it is precisely because of this that he has more questions than other children, and sometimes even his teacher cannot answer.

"Oh? What are the questions? Princess Pingyang also asked curiously when she heard this, she knew that Li Chengdao was an extremely smart child, and there were many knowledgeable masters to teach, what kind of questions could not even be answered by them?

"Aunt Qiyu, my nephew is studying the situation of the Yellow River during this time, the ancient book says that the Yellow River is the longest river in my Central Plains, but no one knows how long it is, in addition, I heard some officials from the south say that the length of the Yangtze River in the south is also very amazing, and it is definitely not under the Yellow River, so my nephew wants to know, which is the longest between the Yangtze River and the Yellow River?"

Li Chengdao said the puzzle in his mind at the moment, but Princess Pingyang couldn't help but be stunned when she heard his words, she didn't think about the question of how long the Yellow River is, as for the Yangtze River, she had heard of it, it is said that the river basin spans east and west, and it doesn't seem to be under the Yellow River, but who of these two is longer, even she has never thought about this problem.

"Auntie, which one do you say is longer, the Yangtze River or the Yellow River?" At this time, Li Chengdao asked again, he seemed to know that it was difficult to ask the length of the Yellow River, after all, unless he measured it himself, it was impossible for others to know.

"This ......" Princess Pingyang didn't know how to answer this question for a while, but soon she had a flash of inspiration, "My aunt really doesn't know this question, but my aunt knows that there is someone who definitely knows!" ”

"Who is it, aunt hurry up and call him to help my nephew answer!" Li Chengdao's eyes lit up when he heard this, he was not only precocious, but also had a stronger desire for knowledge than ordinary children, and these two questions had tormented him for several days.

"That's not good, if you ask someone for advice, you have to make a gesture of asking for advice, and this person is so knowledgeable that he is the only one in my aunt's life, if you have any problems in the future, you can come and ask him for advice, don't be as rude as last time!" Princess Pingyang said with a serious face at this time.

"Last time?" Li Chengdao was stunned for a moment, and then guessed who Princess Pingyang was talking about, and then said with a sudden face, "What my aunt said is that Li Xiu, but he is so young, is he really as knowledgeable as you said?" ”

"Although Li Xianjiu is young, you will know how powerful he is when the time comes!" Princess Pingyang didn't explain too much, she stood up with a smile and said, Li Chengdao was also curious at this time, and immediately followed Princess Pingyang out of the courtyard and walked straight to Li Xiu.

Li Xiu's new home is closer to the princess's courtyard, but it will be there in a moment, when Princess Pingyang entered the courtyard, she saw Yuechan directing several maids to work, and when she saw her, she immediately stepped forward and saluted: "Slave and maid see the princess!" ”

"No need to be polite, is Li Saijiu at home?" Princess Pingyang asked gently, after not seeing her for a while, she also found that Yuechan in front of her had lost a lot of weight, and she was becoming more and more beautiful, but this also made her suddenly a little worried in her heart.

"Princess Qiyu, the lord went out this morning, and just came back and took Qi Niang into the inner house, and he hasn't come out yet, do you need a slave to go in and report it?" Yuechan replied respectfully.

"Well, there's no need to report it, let's just go in!" Princess Pingyang has come many times, and she is also very familiar with Li Xiu's family, so she didn't need to report at all, and came to the inner house directly with Li Chengdao, and soon heard the laughter of Li Xiu's brothers and sisters in the small garden, which also made Princess Pingyang smile slightly.

At that moment, Princess Pingyang took Li Chengdao into the garden, and saw Li Xiu and Qi Niang brothers and sisters on the grass at a glance, but at this time Princess Pingyang was stunned, because she saw that Li Xiu and Qi Niang had a strange thing on their faces, and they actually covered their eyes, and the two were looking around, and Qi Niang let out a crisp laugh from time to time.

"Hey, princess, why are you here?" Li Xiu soon saw Princess Pingyang at the entrance of the garden, and immediately ran over excitedly, and he didn't have time to take off the glasses on his face, which he used some colored crystals for craftsmen to polish, in addition to some other gadgets, he was playing with Qi Niang just now.

"Li Xijiu, what are you wearing on your face?" Princess Pingyang asked in surprise when she saw the glasses on Li Xiu's face.

"Hehe, this is glasses, which are used to block light, and of course it can also be used as a decoration!" Li Xiu said and took off the glasses on his eyes, and then helped Princess Pingyang put them on with his own hands, but Princess Pingyang immediately found that the world in front of her was dyed blue all of a sudden, and the originally dazzling sunlight actually became softer.

"Haha~, the princess is so beautiful wearing these glasses, of course, if you add a sun hat and put on a bikini and lie on the beach by the sea, it will be even more beautiful!" Li Xiu immediately opened his mouth and praised that the glasses were designed by him according to the style of later generations, and then asked master craftsmen to make them, although they were a little unsatisfactory in details, but the general appearance looked similar to that of later generations.

"What is a bikini?" Princess Pingyang asked suspiciously when she heard this, she could barely understand the sun hat, it should be to block the sun, but it was the first time she had heard of the name bikini.

"Hmm~, a kind of dress, very beautiful, I must give it to the princess when I have the opportunity in the future!" Li Xiu was very evil, he estimated that if Princess Pingyang knew what a bikini was, she would probably kill him with a knife, after all, women in this era are still too conservative.

"Auntie!" At this moment, Li Chengdao, who had been ignored, suddenly opened his mouth to express his dissatisfaction, after all, from the moment he first met, Li Xiu chatted with Princess Pingyang non-stop, completely ignoring him, the king of Anlu County, which made him a little angry.

"Huh? Why is the King of Anlu here? Li Xiu had just noticed that there was a child beside Princess Pingyang at this time, which made him surprised, he only paid attention to Princess Pingyang just now, and he really didn't find Li Chengdao.

"Hehe, Dao'er came to visit me today, he couldn't figure out a few problems in his studies, and I couldn't answer them either, so I brought him to ask Li Xianjiu for advice!" Princess Pingyang finally remembered this nephew at this time, and said a little embarrassed at the moment.

"I see, I don't know if the king of the county has any questions he wants to ask?" Li Xiu was a little weak when he heard this, he was worried that if Li Chengdao asked him what poems and songs, and the question of the hundred schools of thought, it would not be difficult for him to steal a few poems, but if he was asked to talk about the knowledge in the poems, it would be difficult for a person like him who couldn't even memorize the Analects.

Li Chengdao Bingxue was smart, and he could see from Li Xiu's expression that he was a little weak-hearted, and he couldn't help sneering in his heart at the moment, and he didn't have any hope for Li Xiu, but for the sake of his aunt's face, he still raised his questions about the Yellow River and the Yangtze River.

When Li Xiu heard Li Chengdao actually ask who was longer in the Yangtze River or the Yellow River, he couldn't help but sigh at the moment, and the expression on his face became very confident: "I didn't expect the county king to draw inferences from one another, and to be able to put forward his own ideas under the teacher's explanation, which is really commendable, as for who is longer between the Yellow River and the Yangtze River, I can tell the county king for sure that the Yangtze River is slightly longer than the Yellow River!" ”

"Really?" Li Chengdao didn't expect Li Xiu to answer his question, but he was still a little skeptical, because he was worried that Li Xiu didn't know at all, but for the sake of face, he said an answer randomly, and no one could prove that he was lying anyway.

"Of course it's true, if I'm not mistaken, the length of the Yangtze River and the Yellow River is more than 10,000 miles, but the Yangtze River is more than 1,000 miles longer than the Yellow River!" Li Xiu replied with a smile, he couldn't remember the specific lengths of the Yangtze River and the Yellow River, but he knew that the two rivers were more than 5,000 kilometers, that is, more than 10,000 miles.

"It turns out that the Yangtze River and the Yellow River are so long!" Princess Pingyang couldn't help but sigh when she heard Li Xiu's words, 10,000 miles is a fairly long distance, she has been fighting in the south and the north all these years, and she doesn't know if she has walked 10,000 miles?

"Haha~, princess don't be surprised, in our Central Plains, the Yangtze River and the Yellow River are indeed the two longest rivers, but for the world we live in, they are not the longest rivers, for example, the Yangtze River can only rank third in the world, and there are two rivers longer than it!"

Men, they like to express themselves in front of their beloved women, and Li Xiu is no exception, but his words suddenly aroused Li Chengdao's curiosity, and he asked eagerly: "Li Xijiu, I don't know what kind of rivers those two rivers are?" (To be continued.) )
