Influenced by his father as a farewell actor, Li Kai learned to dance and sing since childhood. /kloc-when he was 0/7 years old, he was admitted to a song and dance troupe and studied singing and dancing, which made him discover his deep desire for performance.

So after graduating from art school, he told his father that he wanted to go to film school, but many people, including his father, said that he was not suitable to be an actor because he was introverted and his behavior was out of tune with the entertainment circle. However, Li Kai didn't give up this idea. He was admitted to the Beijing Film Academy in 2005, but eventually failed because of his lack of performance experience. After returning home, Li Kai told his father that he would shave his head and not go anywhere. He will prepare his homework for next year's exam at home. It was because of his persistence and hard work that he was finally admitted to Shanghai Theatre Academy. After graduation, he filmed the drama Shunzhi, in which he played the young Shunzhi. From then on, he began his career as an actor.
