On Monday morning, it was a basic class in ancient Chinese, and there was no class in the afternoon, so Gu Yu planned to go to the library to borrow a copy of "Appreciation of the Book of Changes". After a lunch break, she got up and went to the library to borrow books, and soaked in the library for an afternoon.

The orange sky is dyed with pink clouds, from near to far, from light to deep. It's like the sky in Japanese comics.

In the stands, Li Xiang has already placed the water, all pure water, and the price varies.

Li Xiang got up and clapped her hands after setting it up, expressing her very satisfaction with her stall.

In the afternoon, the temperature in Dihai is not high, and the sea breeze blows with a hint of coolness. There were a lot of people running on the playground, and Gu Yu couldn't see Li Xiang anymore. Sitting a little bored, she took out "I Ching Appreciation" and began to read.

Gu Yu's hair up to his waist was black and shiny. There are a few strands of bangs on the sideburns, allowing the wind to fiddle at will. At this moment, the poetic sky instantly became her background color.

Reading the part he likes, Gu Yu will smile unnaturally, with bright eyes and bright teeth, and a greasy face, like a gentle and delicate dynamic comic.

From time to time, panting girls come to buy water.

When night fell, Li Xiang's income was good, and her mobile phone had entered a lot of accounts, and she was counting the money.

After putting away the stall, she returned Gu Yu's sports bracelet to her. It's been a busy afternoon, and I haven't eaten dinner yet. Both were a little hungry and decided to go out for a bowl of noodles.

A short and thin boy came in front of him, Li Xiang didn't see him, and rubbed his shoulders against him.

"I'm sorry!"

"I'm sorry!"

The two spoke in unison, and as soon as they raised their heads, Li Xiang was surprised: "Senior! ”

Xu Boyu is their class assistant, the same Chinese language and literature, and he notified the major news in the group during the period from the time the freshmen entered the school to the military training.

Xu Boyu pushed the black-framed glasses and said, "It's you!" Seeing the bracelet in Gu Yu's hand, he asked, "Come to check in and run?" ”

Li Xiang said: "Yes! ”

Xu Boyu hesitated for a moment, pointed to the mineral water at Li Xiang's feet, and asked, "Then what is?" ”

Li Xiang's business brain was surprised, and she seized the opportunity to start publicity: "I'm selling water here!" Can the seniors go back and help me promote it? ”

Xu Boyu nodded, with an expression on his face that the back waves of the Yangtze River pushed the front waves, and one wave would make more money than the other: "Okay!" ”

Xu Boyu returned to the dormitory, and everyone in the dormitory was there. Sishi was the first to spot him, "Brother Bo, how is the game?" Xu Boyu participated in the finals of the poetry conference in the imperial capital on behalf of the school in the summer vacation, and missed the flower by one point.

In addition to him, the other three big men in the dormitory are all pure science men, and in addition to asking about grades, they can only ask about grades.

Xu Boyu said the ranking, and Haichang said: "Brother Bo, it's enough to be fourth in the country!" ”

Sishi's language level is not as good as Haichang's, he always thought that Xu Boyu participated in a local competition, and he pulled his voice: "Fourth in the country!" Xu Boyu, did you secretly carry us to the middle stage?! ”

Haichang said: "Brother Bo has long said that he is going to participate in the poetry conference. ”

Sishi sighed a few times, pulled over the stool and sat down in front of Xu Boyu, his eyes narrowed: "Brother Bo, we have to celebrate if you win the award, don't we!" “

Xu Boyu asked, "How to celebrate?" ”

Sishi said confidently, "Eat! How else can we get together, and we can't do illegal things. ”

“……”

The place to eat was a grilled fish restaurant outside the school. In order to fit the theme, each seat is a converted boat, Guo Shan chose the largest sailboat, a round table, and everyone sat down one by one.

Usually they eat together with boys, but today there is another Li Xiang, and everyone can't help but be curious.

One of Guo Shan's roommates asked, "Sishi, your girlfriend?" ”

Li Xiang, who was sitting next to Sishi, was the first to refuse: "No, no, I'm here to eat." ”

Li Xiang was pulled over by Sishi, and there were a few friends in the bedroom next door for this party, and the annoying thing was that they all brought their girlfriends.

Sishi felt that he had to raise his eyebrows, but he had no girlfriend, so after thinking about it, he tentatively asked Li Xiang if he would like to come together.

Of course Li Xiang is willing, she is working hard to make money in order to buy concert tickets, and she can save money.

After arriving, Li Xiang regretted it, she was a girl sitting in the pile of 8 big old men, and Li Xiang always felt that she had a needle in her buttocks. She excused herself to go to the toilet and called Gu Yu for help.

"Gu Xiaoyu! Where? Come out to eat. Afraid that she would regret it, Li Xiang immediately hung up the phone.

Ten minutes later, people came one after another, and Li Xiang realized that she was thinking too much, and among the people who came, there were also a few senior sisters who had added her WeChat when the freshmen registered.

She couldn't wait for Gu Yu to come over quickly.

At the round table, everyone had a casual chat.

After all, today is all for Xu Xiucai, but everyone doesn't understand literature, Guo Shan can only ask casually: "Brother Bo, why did you miss the third place by one point at that time!" ”

Speaking of this, Xu Boyu had some regrets, he was unlucky, and drew an unpopular literary question, the title of which came from the "Book of Changes", asked: The source of the sentence "Heaven is born of water, and the earth is sixty percent" from which day.

The sky is an expression of nature, Xu Boyu has read the Book of Changes, but its content is difficult to understand, he has only read it. Didn't dig deeper.

In my memory, I've heard this sentence, but I just can't remember it. Before the final answering time, he chose Vena.

He cleared his throat and said, "Carelessness in Jingzhou." After a pause, his literary sermon began: "This question is a bit out of the way, and the books of Hetuluo are all hanging from the sky, one is from Ryoma, and the other is from ......."

Guo Shan stopped him in time: "Stop, stop!" Brother, we don't want to know how biased the topic is, we want to know what the answer is. ”

Xu Boyu said: "Hetu. ”

Guo Shan: "Hetu? Who drew it? How much is it worth? ”

Xu Boyu was a little depressed in his heart, he was always not on the same channel as this group of people. Li Xiang had already returned from the bathroom, and there were a few more girls on the round table, who were the girlfriends of the other two boys in Guo Shan Jiang Liwei's dormitory.

After Li Xiang sat down and listened to them, Sishi later realized that "Li Xiang, aren't you learning Chinese language?" How much is this river map worth? ”

Li Xiang hurriedly waved his hand, "I was transferred, and I don't understand." Then she thought of Gu Yu and said, "But someone must know!" ”

Xu Boyu became interested and asked, "Who?" ”

"Gu Yu!" She added, "She reads this book every day!" I've been reading it lately. ”

Finishing and understanding are two concepts. Xu Boyu thought.

Li Xiang's mobile phone rang, and she jumped up: "It's just right, Gu Yu is here." I'll go down and pick her up. ”

Sishi, who had experienced the last fat cow game, rushed to say, "Brother Shu, you called?" ”

Xia Shumang's eyelids twitched, he didn't even have Gu Yu's contact information, how could he call it? Flying Pigeon Biography?

He replied lightly: "No." ”

Li Xiang's speed was very fast, and he took Gu Yu to the round table three minutes later.

She changed her hairstyle, tied her balls, and the fine bangs on both sides made her already small face even more cute.

Xia Shumang's eyelids twitched again.

Gu Yu sat next to Li Xiang, two people away from Xia Shumang. Once she was seated, the conversation continued.

Sishi first said: "Gu Yu, Li Xiang said that you have been reading the Book of Changes recently, tell us how much the river map is worth?" ”

Haichang patted him, "Qian Qian Qian, our dormitory has a show of talent, can you have an artistic atmosphere when you talk in the future?" After thinking about it for a while, Haichang changed his question and asked: "Gu Yu, is it difficult to draw the river map?" ”

Gu Yu pondered for a while and said, "Hetu! It's simple. ”

After speaking, Gu Yu picked up the water cup and poured some water on the table, dipped it with his hand, and drew it in front of him.

A few seemingly regular points, some lines of different lengths, and in a minute, a river map was drawn.

The fragments in the depths of Xu Boyu's memory were put together little by little, and finally, after Gu Yu finished painting, he shouted: "Yes, yes, yes!" This is the river map! ”

Everyone present sighed and looked at the symbol in front of Gu Yu. The painting is simple, but it is messy and has no beauty. Sishi was closer to Gu Yu, and he couldn't help but feel a little lost: "This is Hetu?" I thought it was priceless. As soon as the conversation changed, he said to Xu Boyu: "Brother Bo, these points stumped you?"

Xu Boyu retorted: "The river map contains the mystery of the world's meteorological numbers, and these points and lines are very knowledgeable!" ”

Xu Xiucai did not talk about the big reason as before this time, because he couldn't say what each point of the river map represented.

Xu Boyu carried forward his good quality of asking questions if he didn't understand, and asked as if he didn't believe it: "Gu Yu, what do these dots and lines mean?" ”

Gu Yu explained with a smile: "Hetu is also a branch of mathematics. She put her hand on the north of the picture, "one white and six black, for water." ”

Xu Boyu hurriedly said: "Yes, yes, yes!" The sky is water, and the earth is sixty percent! "That's his exam question.

Gu Yu pointed to the southeast and west in turn, "three white and eight black, for wood; two black and seven white, for fire; Four black and nine white, for gold! ”

Sishi hurriedly asked, "What about the middle one?" ”

"Five white and ten black, for the earth."

"What is black and white?"

Xu Boyu was present, and Xia Shumang, the only person with rich literary knowledge, said: "Yin and Yang." ”

Gu Yu glanced at him in surprise, "It's yin and yang!" ”

Xu Boyu also wanted to know more, "I understand the arrangement of the five elements, but what does this number represent?" ”

Gu Yu paused and said, "1, 3, 5, 7, 9 are yang, 2, 4, 6, 8, 10 are yin. As mentioned above, the sum of yin and yang is all 5. ”

Everyone here has a very good memory, looking back at what Gu Yu just said, indeed, the sum is all 5.

A new question came again, Xu Boyu: "What does adding up to 5 mean?" ”

Gu Yu said unhurriedly: "The number of heaven and earth is five out of fifty."

Everyone present was stunned when they heard this, and Guo Shan asked Xia Shumang: "Brother Shu, what is this little girl talking about?" ”

This question seriously involves the knowledge blind spot of the science and engineering men present, Xia Shumang said casually: "Maybe you have five out of fifty - two hundred and five!" ”
