In 1969, almost all families in China were about to face the choice of going to the mountains and rural areas.There is a Zhou family in Guangnpian, Liaoning Province, who are also overwhelmed by this choice of going to the mountains and countryside.Zhou Zhigang is a third-line worker in the university. He has three children in his family. The eldest Zhou Bingyi has joined the Construction Corps, the second has a daughter named Zhou Rong, and the third has a son named Zhou Bingkun.According to the policy, both men and women must go to the mountains and countryside. Aunt Qiao on the street came to work and persuaded her to have another child. However, in Aunt Qiao's opinion, Zhou Rong was a girl, and she was very good-looking.The boy was thinking that it would be even more unsafe if he went to another place.Now Lao Sanzhou Bingkun has graduated from junior high school, so they all hope that Zhou Bingkun can go.

Zhou Rong insisted on going to the countryside, but Zhou Zhigang's wife couldn't make up her mind for a moment and couldn't speak. Zhou Zhigang came back after taking the photos. He developed a total of five photos, one photo for each person. Everyone knew that they were separated this time, but they didn't know how long it would take to see each other again..Zhou Zhigang finally asked Zhou Bingkun to go to the countryside. Zhou Bingkun himself was very happy, and the family agreed.

The Zhou family came to the station to see off Zhou Bingyi first. Zhou Bingyi had a smile on his face, turned his head and shed tears, and still clutched the money his mother secretly gave him.Thirty minutes later, Zhou Zhigang was sent away. Zhou Zhigang and his wife looked at each other in tears, but neither could say what they wanted to say. Zhou Rong took the initiative to let Zhou Bingkun pick her up and kissed Zhou Zhigang's face through the car window, twice in a row.The lower one represents oneself and the lower one represents the mother.Zhou Zhigang couldn't bear to leave his family, but he had to go out.

Zhou Zhigang has gone through two major changes in his life. For the first time, he became a third-tier construction worker and changed his rural household registration to urban household registration. However, now that he has moved to the mountains and countryside, his two children will lose their urban household registration.

Zhou Bingkun gave all the books left by Zhou Bingyi to Zhou Rong for safekeeping. All the 61 books inside would be out of print. Zhou Rong was worried that it would be unsafe to store them at home, so he picked them up with an oilcloth and put them in a pile of cabbage. Zhou Bingkun proposed to use peppers to prevent insects., Zhou Rong laughed hard at Zhou Bingkun and reminded Zhou Bingkun that he must study more and graduate from junior high school just like graduating from elementary school.

Cai Xiaoguang sent Zhou Rong away from home. Zhou Rong got into the car without telling everyone, leaving only a letter telling Zhou Bingkun to take good care of her mother. She went to Guizhou to go to the countryside.Cai Xiaoguang went to Zhou Rong's mother on the third day and told the reason. Feng Huacheng, whom Zhou Rong liked, was in Guizhou. Cai Xiaoguang had always liked Zhou Rong, but Zhou Rong only liked Feng Huacheng.Cai Xiaoguang has been pretending to be Zhou Rong's boyfriend these years, just to block those suitors.In Cai Xiaoguang's eyes, Zhou Rong is great and can go to the mountains of Guizhou for love, but this makes Zhou's mother sad and worried.

A few years later, when everyone grew up, Zhou Bingkun was working in a factory. On this day, the factory suddenly notified Zhou Bingkun to participate in an event where he would shoot a child.Zhou Bingkun was unwilling to go, claiming that he was timid, but the factory insisted that Zhou Bingkun must go, and believed that Zhou Bingkun should also take a warning and go and have a look.Tu Zhiqiang is a very good friend of Zhou Bingkun. Zhou Bingkun has always taken good care of him. When the two of them carry wood to work, Zhou Bingkun will lift the thicker ones and let Zhou Bingkun carry the thinner ones.

There were many people gathered at the door of the detention center, and it was snowing. Everyone who was killed was wearing a hat, except Tu Zhiqiang.Zhou Bingkun wanted to give his hat to Tu Zhiqiang several times, but he didn't have the courage. Suddenly a man in a suit gave his hat to Tu Zhiqiang.Tu Zhiqiang seemed to have said something to him, but no one heard it. The man in the suit just told the guard that those were the words of Tu Zhiqiang thanking him.

When they arrived at the shooting place, they were surrounded by people watching. After the gunshot, everyone's eyes widened, except Zhou Bingkun who fainted on the spot.Everyone gathered around to watch, and the man in the suit also came to watch. Only then did they realize that Tu Zhiqiang was Zhou Bingkun’s friend, that’s why he was frightened and fainted. The man in the suit also muttered Zhou Bingkun’s name silently, and said it in the ear of his accomplice.What Tu Zhiqiang said at that time seems to be related to Zhou Bingkun.

Qiao Chunyan came to Zhou Bingkun and asked about Zhou Bingkun's affairs at the execution ground. Qiao Chunyan had always liked Zhou Bingkun, but Zhou Bingkun did not notice it.Zhou's mother was going to pour the swill. Zhou Bingkun rushed over with the bucket, and Qiao Chunyan took the initiative to accompany her.Zhou's mother has been crying since Zhou Rong left. Now her eyes have been seriously injured and she can't see clearly.

When Qiao Chunyan and Zhou Bingkun were pouring swill, the man in the suit and the currency Luo Shibin followed, but the man in the suit did not dare to come forward after seeing Qiao Chunyan. Qiao Chunyan had seen him and Tu Zhiqiang together.
