This movie is about time travel, but this time travel is not back to ancient times, but back to the time when Xu Zhengtai, the father of the male owner, was born. It is a comedy with clever conception, laughter and tears, which is worth remembering. At the beginning of the movie, A Lang won the racing championship, but he was still kicked in the face by his father, who wouldn't let his children do what they liked and disciplined them with violence. The contradiction between father and son is a major attraction, and how to resolve the misunderstanding between father and son has become the main line.
Tracing back to his father Xu's youth, A Lang joined the "Zheng Tai Gang" full of ideals. On the surface, they are bohemian, but in fact they are just a group of idealistic youths in a small town. "Zhengtaibang" sticks to the ballroom only because Mommy is Xu's lover, and the eldest brother who seems to be able to give orders is just fighting for the person he loves the most. The most realistic one is Ma Xiao, who left the town to realize his dream. He really doesn't belong here. Accurately speaking, all dream catchers do not belong to the town where they grew up.
The town has given birth to an ideal teenager, so it is necessary to hope that he can go out and see a wider world. Han Han returned to his former town from that vast world, but when he was mature, he looked back on his youth in order to pay homage to his idealistic self. He expressed his nostalgia for youth in the form of comedy.
