Gu Yu expressed her ambition to Zhang Guimei. She planned to apply for Yunnan Normal University and promised to return to Nanping Girls' High School after graduation to continue Zhang Guimei's educational career.However, Zhang Guimei has reservations about this. She believes that Guyu should pursue a broader future instead of being limited to the mountains.But for Gu Yu, becoming a teacher, especially a teacher like Zhang Guimei who can influence the destiny of others, is her unwavering dream.

At this time, the hospital called to inform Zhang Guimei that Cai Guizhi's father was admitted to the hospital urgently due to cerebral infarction. Although he was out of danger, he had to be bedridden for a long time. The cost of surgery was as high as 60,000 yuan.After Zhang Guimei's visit, she left a good impression on Yuan Shuai, who was waiting in the corridor.Yuan Shuai also deeply understood Zhang Guimei's intentions because of this incident, and decided to break up with Liu Xiying and focus on his studies, believing that only knowledge can change destiny.

Liu Xiying was heartbroken because of the breakup, and there were constant cries in the dormitory. Gu Yu felt helpless and revealed Master Cai's condition to everyone.Cai Guizhi had to take care of her father and faced dual financial and academic pressures. She once considered dropping out of school.After Zhang Guimei learned about it, she took the initiative to apply for work-related injury insurance subsidies for the Cai family, which alleviated their financial difficulties.

However, Cai Guizhi was still worried about her father's health and future living expenses, and finally submitted an application to drop out of school.Zhang Guimei was deeply saddened, and the teachers also planned to go to the hospital to persuade her.The next day, Zhang Guimei sent meals to Cai Guizhi, but she saw that she was sleeping soundly and did not have the heart to disturb her.At this time, Gu Yu led the mock test with the first score in the school, while Cai Guizhi insisted on completing the test paper even at the hospital bedside.

In order to encourage Cai Guizhi to return to school, the classmates staged a drama of “acute gastroenteritis”.Zhang Guimei saw through Gu Yu's plan, but still took her to see Cai Guizhi and gave her a precious hour of communication time.Guyu used his own experience to comfort Cai Guizhi, emphasizing that education is the only way to change destiny.After Master Cai woke up, he motioned to Zhang Guimei through his eyes to check the test papers in the drawer. This scene deeply touched Zhang Guimei.

The students also made paper cranes to express their thoughts and support for Cai Guizhi, which made her burst into tears.The next day, Gu Yu added Cai Guizhi's name on the score list, inspiring the admiration and envy of the whole school.Zhang Guimei realized that schools should not only pay attention to students' academic performance, but also comprehensively care about their growth and needs.

In the end, Cai Guizhi decided to return to Huaping Girls' High School under the expectation of everyone. She excitedly ran to Zhang Guimei's office to report her return, made a detailed time planning form, and re-filled in her application for Kunming Medical College.The students warmly welcomed Cai Guizhi's return with warm little playing cards. The slogan "The boat has passed the Ten Thousand Mountains" means that they have overcome many difficulties and officially entered the critical sprint stage before the college entrance examination.
