Wen Jie used the allowance in his hand to go to the store to buy ten yuan cream, intending to give it to Lin Huajun. Cheng Jiashu and Bi Yunxiao looked for Nature Magazine together, wanting to read the articles on it. At this moment, the two met Ye Runqing and Luo Heng. When Ye Runqing saw them, he had a complicated expression on his face and ran away without saying hello. Luo Heng knew that Runqing was in a bad mood, so he flew a plane with Runqing around Kunming to make sure that she would forget her troubles. Luo Heng pretended that the plane flew over Mengzi, and Runqing fell into memory. He said that the next stop was Wuhan, where Ye Runming died. She didn't know if flying like this would bring her closer to Ye Runming. In fact, Ye Runqing has never been able to let go of her brother's death. It was her brother who had blood with her more than water.
The summer vacation is coming soon, and the community organizes summer camp activities. Pei Yuanzhi proposed several plans and asked for everyone's opinions. Cheng Jiashu's suggestion is to have a better understanding of Yunnan and measure every inch of land here with your feet. It just so happened that Professor Chen Da was organizing a county-level social administrative survey and study, and Pei Yuanzhi suggested that the community set up a summer survey team and participate in it. Bi Yunxiao agreed with both hands, and it was his regret not to be able to participate in the tour group. Cheng Jiashu wrote a handwritten letter and sent it back to his family in Peiping. The long-distance trek is about to begin, Cheng Jiashu taught everyone leggings, and he couldn't help but think of Ye Runming. Ye Runming taught him this leggings, and now he is teaching other students in a decent manner, which is equivalent to a kind of inheritance. Thinking of Ye Runming, Cheng Jiashu feels sad.
Before leaving, Cheng Jiashu discovered that the Three Youth League also went to participate in the county social administrative survey, and they happened to go to the same place with them, that is, Yuxi where Lin Huajun lived. Wen Jie's expression changed when he heard that Cheng Jiashu and the others were going to Yuxi as well. A group of the Sanqingtuan went to Yuxi in a carriage, so Wen Jie arrived at Yuxi first. After talking to Zhu Xiuyuan, he went out of the city to Yulin Primary School to find Lin Huajun. At that time, Lin Huajun was teaching the children to read. These were girls from the nearby villages. The family did not want to pay for them to study, so Lin Huajun taught them during the summer vacation. Wen Jie asked if there were any vacant rooms here. He wanted to stay with Lin Huajun and teach together. In fact, he wanted to win Lin Huajun's heart one step ahead of Cheng Jiashu.
Lin Huajun sternly refused and asked him to take the cream back. Wen Jie probably also realized his abruptness, and was very embarrassed. He took the box and left, looking like he was running away. Back at the inn, Wen Jie excused himself from feeling uncomfortable and did not attend the reception banquet hosted by the county magistrate. Pei Yuanzhi took Cheng Jiashu and others to an old man's house in the village. Today they went all the way to investigate and visited a hundred families. After Cheng Jiashu finished writing his diary, he went out to chat with Pei Yuanzhi. Cheng Jiashu and Mr. Pei talked about a child Guisheng they met in the previous tour group. He didn't understand it at the time, but now he finally understands how to help these poor families. Pei Yuanzhi could see that the spirit of Runming had infected Cheng Jiashu, and Cheng Jiashu was becoming more and more like Runming.
The next day, they continued to visit and investigate. Cheng Jiashu was picking up water for Bi Yunxiao, and Pei Yuanzhi reminded him that Yulin Primary School was ahead, and whether he wanted to take a look at Lin Huajun. Cheng Jiashu still went to Yulin Primary School and met Lin Huajun whom he hadn't seen for a long time. Knowing that they have no place to stay, Lin Huajun suggested that they live in the school.
