In old Shanghai in 1927, Liu Xuyin met Meng Langping in a piano shop on the street. That era was really turbulent, and it was also an era of the rise of new ideas.
Meng Langping: "Where do you want to go after the war is over?"
Liu Xuyin: "I don't know, maybe I won't want to go when the time comes."
Purpose: To describe the impact and changes in social life in the Republic of China under the wave of the new era, as well as the love outlook, ideals and melancholy of young people affected by new ideas, as well as their fearless devotion to their country in times of crisis.
