Synopsis：A group of young people organized a class reunion and invited a respected teacher 李雪 (played by 柳智玉). 李雪 was admitted to Guangxi Normal University in 1995, becoming the first university student from the mountain region, but she gave up the opportunity and chose to stay in the village as a volunteer teacher for the children. Initially, her parents strongly opposed her decision, but her determination to be the children's teacher remained unchanged. Her childhood sweetheart boyfriend 陈东 (played by 雷启飞) was very supportive. 李雪 said that she gave up the chance to attend university so that all the children in the mountains could go to university. Despite numerous difficulties during her volunteer teaching—lack of pens, textbooks, and even a classroom collapse—she overcame them one by one. Her story moved the government and the education bureau. With the care and support of the Party and the government, they received a new school building, new schoolbags and stationery, and the left-behind and out-of-school children in the mountains were able to receive an education.
