Lin Xiaoman, a fourteen-year-old girl who was tired of studying and rebellious, shouted out "time travel" out of anger due to a quarrel with her mother, and unexpectedly fell into the war-torn Kunming of 1938. Instead of waiting for a comfortable modern life, she faced air raids, bombings, and displacement in troubled times. When she was desperate, she was taken in by the gentle Professor Shen Qingyuan of Southwest Associated University. In simple mud houses, tin classrooms, and air-raid shelter classrooms, she witnessed with her own eyes the character of the people and gentlemen of the Associated University who persevered in their studies and protected their cultural heritage in desperate situations. From questioning the "uselessness of studying" to understanding the righteousness of her family and country, from being rebellious to standing up to protect others, she completed the transformation in the fireworks and the dim light of the fragrance of books in troubled times, and finally returned to modern times with the faith engraved in her heart, said goodbye to being tired of studying, and lived as a young man with light in her heart. This is a journey of growth through the flames of war, and it is also a hymn to youth that pays tribute to the spirit of Southwest Associated University
