One's Olympic Games tells the story of how, in 1932, Chinese athlete Liu Changchun overcame countless difficulties and dangers to stand on the starting line of the 100 meters at the Los Angeles Stadium. For this moment, Liu Changchun refused to represent the puppet state of Manchukuo supported by Japan in the 10th Los Angeles Olympic Games. He tearfully bid farewell to his wife and children, escaped from Dalian occupied by the Japanese, and evaded the pursuit of the Kwantung Army. With the help of General Zhang Xueliang, he traveled by sea for days alone to attend the conference and represented four hundred million Chinese people standing on the track of the Olympic Games. He opened the door to the Olympics for the Chinese people and expressed to the world the strong will of a nation not to fall behind and not to be humiliated while chasing after the world.
