At the end of a street, Qi Yue saw that the night was getting dark, so he took Song Cheng and Qi Chen back.Halfway through, Qi Chen went back by himself, leaving only Qi Yue to lead Song Cheng back.

Song Cheng was afraid of the dark, so he only followed behind Qi Yue. He raised his eyes to look at the night sky, and saw the stars twinkling in the sky, one of which was particularly bright.Song Cheng pointed to the star in the sky and said, "Qi Yue, I bet you that that star will become as dazzling as the moon."

Qi Yue followed Song Cheng's gestures and looked over, he smiled and said, "Just talk nonsense, how could the stars shine as brightly as the moon? Children talk nonsense."

Song Cheng said, "What I said is true."

Qi Yue smiled and said, "Then let's bet, what if you say you lost?"

Song Cheng "cut" and said, "How could I lose!"

"If you lose, give me back the slingshot!" Qi Yue was thinking about his precious slingshot, and he immediately raised his bet to Song Cheng.Song Cheng gave him a disgusted look, "No prospect, just remember that slingshot."

Qi Yue said with a "Hey", "You are worthless, you are worthwhile, you give it back to me."

Song Cheng bent his eyes and said, "No." He added, "I bet that in 26 years, this star will become as dazzling as the moon."

Qi Yue said with a "huh", "You are amazing, you think you are a fortune teller or a celestial inspector, and you know how to watch stars, and you even know this."

Song Cheng rolled his eyes, "We're home, do you still want to gamble?"

"Gamble! Why not bet!"

Song Cheng smiled and said, "If you lose, you promise me one thing, how about it?"

Qi Yue asked, "What's the matter?"

"I haven't thought about this yet, let's talk about it after you lose."

"Okay, you have the final say! What if you lose?"

"I won't lose."

Qi Yue and Song Cheng leaned under the big willow tree to watch the stars, he looked at the stars in the sky and asked, "How many stars are there in the sky?"

Song Cheng let out a "puchi" laugh, and suddenly remembered a romantic and toothache saying, he said solemnly, "The stars in the sky are the eyes of the dead shining in the sky, in the dark night sky, guarding this own Lover. Therefore, there are as many stars in the sky as there are dead on the earth.”

Qi Yue smiled and said, "Nonsense, I don't believe it, don't move and let me count."

Qi Yue's counting became messed up after a while, so he went back and started counting again, while Song Cheng squatted aside to watch him count.Qi Yue said, "How about you count for me, I will count from the east, and you will count from the west."

Song Cheng yawned and said, "Zhang Heng didn't even count, can you?"

"Who is Zhang Heng?" Qi Yue simply stopped counting, and leaned against the big willow tree together with Song Cheng to talk.

Song Cheng said, "Zhang Heng is an astronomer in the Eastern Han Dynasty. He counted the stars like you when he was a child, but he didn't count them." He paused and said, "The stars in the sky are always moving, but between them The relative position between them is certain, and you have to divide the constellations in order to have a way to count them.”

Qi Yue was confused, "What is relative position?"

Song Cheng frowned and thought for a while, "The two stars are both moving, but the distance between them remains the same. It's like the two of us running on the road, you have been following me, and others saw us moving , but the distance between us remains the same, this distance is the relative position between us.”

Qi Yue said "Oh" with a confused face, "You know a lot."

Song Cheng added in his mind, "This junior high school student knows it all."

"Do you know how many stars there are in that day?" Qi Yue asked.Normally, he was always like the little bully, but now he suddenly quieted down, Song Chengjue was fine, and he wished that Qi Yue could always be a quiet and handsome man.He was thinking wildly in his head, but his mouth was very clear, "There are about [-] stars that can be observed with our naked eyes, but if they can be seen during the day, there should be nearly [-]."

"So many!" Qi Yue sighed, "How can there be stars during the day, the stars only come out at night."

Song Cheng said, "It's just that the sun's light is too bright, covering up the dim stars."

"how do you know?"

"Read more!" Song Cheng stood up, patted the dirt on his body, and gave Qi Yue a box of preserved fruits bought at the night market, "Take it back to Aunt Qi, I'm going back."

Qi Yue took the box and asked Song Cheng, "What are you doing tomorrow?"

"I went to visit a friend of the teacher with the teacher." Song Cheng said.

Qi Yue said "Oh", "Then I'll go back."

Song Cheng nodded and went back.When he opened the door of the library, he saw Master Xu writing something with a lamp on in the corner. He bowed and said, "Teacher."

Master Xu didn't look up, he just wrote vigorously, "Are you back? Go and tell your teacher's wife to go to bed early, we have to go out tomorrow morning."

Song Cheng nodded and said, "Yes."

In the early morning of the next morning, Mrs. Xu woke up Song Cheng at dawn. Mrs. Xu specially changed Song Cheng into new clothes, and gave many instructions, such as being polite to the old gentleman, he has a bad temper and so on.Song Cheng just nodded obediently, and wrote down everything the teacher said.Master Xu said, "Stop rambling, we are leaving."

Mrs. Xu let Song Cheng go, Master Xu took Song Cheng to the clinic to sell some medicine and bought some meat, and then took Song Cheng out of the city.After walking for about half an hour on the road, I arrived at Mr. Cui's house.

Mr. Cui's family lives at the foot of the mountain. There is a pool of clear water in front of the door, two big willow trees are planted, and the courtyard wall is low.Master Xu walked to the door, knocked on the door and said, "Old Cui." He heard a cough from inside, and an old voice said, "Old Xu is here? Come in quickly."

Mr. Xu led Song Cheng into the door, until they arrived at the place where Mr. Cui lived. Song Cheng heard from his teacher's wife that Mr. Cui was very fierce, so he didn't dare to hack around, but followed Mr. Xu obediently.Mr. Cui was half lying on the bed, flipping through a notebook in his hand. He saw Mr. Xu bringing Song Cheng in, smiled and said to Mr. Xu, "Is this the student you selected?"

Master Xu smiled and patted Song Cheng's head, "Yes, bring it here for you to see."

Song Cheng hurriedly bowed and said, "Student Song Cheng has met Mr. Cui."

Mr. Cui stretched out his hand to help Song Cheng up, he grabbed Song Cheng's hand, smiled and said to Master Xu, "He is a decent child."

"That's natural. The child that Xu Jingzhu likes is naturally good." Master Xu said with a smile.

Mr. Cui seemed to be stimulated, he coughed violently a few times, Song Cheng helped him take the water glass beside the bed and handed it to Mr Cui, Mr Cui took it with a smile in his eyes, he smiled and said, "Is it my Poor eyesight? I fell in love with him when I was young and wanted to take him in as a student, but this kid went to join the army without saying a word!"

Master Xu followed with a sigh and said, "What's the use of saying this now? It's been three years since he's been away. He won the battle this year, and he doesn't know when he will come back."

Mr. Cui snorted coldly, "He will be a little general when he comes back, I dare not accept him as a student!"

Master Xu smiled and said, "Slow down, why are you so angry? I can do it?"

Mr. Cui glared at Mr. Xu and stopped talking. Mr. Xu asked with a smile, "Where's Pingzhi? Why didn't you see me today?"

"I went to the mountains to collect firewood. There is no fire at home for a few days." Mr. Cui was still a little annoyed, but there was a bit of kindness in his eyes.Song Cheng stood aside without daring to say a word, only watching his nose and heart.

"Pingzhi is my son. He is older than you, and he is simple and honest. When he comes back, let him take you out for a stroll." Mr. Cui panted.

Song Cheng was flattered and looked up at Mr. Cui, with the expression that you are talking to me.Mr. Cui understood the question marks in his eyes, smiled and said to Mrs. Xu, "It must be Mrs. Sister-in-law who said something to this child, so afraid of my old man."
