Ye Runqing's attitude towards Bi Yunxiao was indifferent, Bi Yunxiao stood there awkwardly, then Luo Heng took a bouquet of flowers and a box into the ward, her attitude towards Luo Heng was obviously better than that towards Bi Yunxiao, Bi Yunxiao knew it was unnecessary, and soon leave. Knowing that Ye Runqing was ill, Lin Huajun was also worried about her, but she was too busy to contact the country school right now, so she couldn't help the two elders of the Ye family go to the hospital to take care of Ye Runqing. Lin Huajun decided to take a leave of absence from school. She was going to teach in a rural school in Yuxi and started to learn about people's wisdom. Zheng Tianting persuaded her to think carefully, but Lin Huajun had already made up her mind, so Zheng Tianting said that the school would always keep her corresponding student status. Cheng Jiashu saw the diary left by Ye Runming, and after being inspired, he wrote down his application for changing departments.
Pei Yuanzhi also felt that physics was more suitable for him, and agreed to help him with the application for the transfer. Pei Yuanzhi knew that Ye Runming's death had affected many people around him. He told Cheng Jiashu that Lin Huajun had decided to teach in a rural elementary school in Yuxi. Ever since he lost his mother, Lin Huajun had been alone. The elementary school she went to was very difficult in the countryside, and a girl she had no one to rely on would definitely suffer. Pei Yuanzhi hoped that Cheng Jiashu and Lin Huajun would come out of the pain and face their hearts bravely. Luo Heng went to the hospital to see Ye Runqing, Ye's mother and Ye's father refunded the ticket to Hong Kong, because they really couldn't let Runqing go. Luo Heng went in to persuade Ye Runqing, Xiaozhi moved him with emotion and reasoned, Runqing listened to his words, and finally said that he wanted to eat.
Lin Huajun went to the teahouse to bid farewell to A Mei. She couldn't bear to tell her the news of Ye Runming's death, but she just said that Ye Runming had gone far away, and she was also going to Yuxi to teach, and Amei's homework was tutored by Wen Jie. Father Ye wrote a letter to Cheng Jiashu, and when Cheng Jiashu saw the letter, he and Mother Ye had already set off for Hong Kong. Father Ye enlightened Cheng Jiashu in the letter, and hoped that he would not blame himself too much, walk the next road well, and fulfill Ye Runming's unfinished dream. On the day Lin Huajun left for Yuxi, Cheng Jiashu went to see her off. Lin Huajun told Cheng Jiashu that Amei came to Kunming and opened a teahouse, saying that she would wait for Ye Runming to come back and continue to learn from him. After saying these words, it was getting late, and Lin Huajun got into the carriage and left.
Ye Runqing cheered up, and Luo Heng took her to meet his flight instructor. When Lin Huajun arrived in Yuxi, teacher Yang Minghui from Yulin Primary School gave her a brief introduction to the situation of the primary school and took her to the dormitory to settle down. Lin Huajun packed her luggage by herself, and saw the combination of numbers and shapes that Cheng Jiashu had given her. Cheng Jiashu looked at Ye Runming's diary, and he suddenly understood a lot of truths. Only a strong nation is the foundation of survival. If you want to save the nation, you must save the nation scientifically. For students like them, the only way to survive is to study hard. The way to save the country. Cheng Jiashu has a talent for science. Professor Zhao Zhongyao said that he can transfer to the Department of Physics and start directly from the second grade. Soon, Bi Yunxiao introduced him to everyone.
Pei Yuanzhi submitted an application to his superiors, and he wanted to marry Fang Yuerong. According to the organization, as long as Fang Yuerong agrees to sign the application, the organization will not interfere. But after Fang Yuerong went through the tragic experience in Wuhan, marriage was not that important to her. She said that she could not marry Pei Yuanzhi, and she could not even disclose their relationship. Before meeting Pei Yuanzhi, she went to see Guo Tielin, but did not sign the application.
