Zhao was born in Lanzhou, Gansu. He attended and graduated from Shanghai Theater Academy and performed as a dancer for ten years. Throughout the years, he participated in many national and international dance competitions and has also acted as a choreographer. Before graduating, the academy wanted Zhao to stay and serve as a teacher, but he was diagnosed with a serious knee injury that forced him to quit dancing. After that, he decided to become an actor and starred in his first television series, KO One Re-member, in 2016 and officially entered the entertainment industry.

On July 14 of the same year, Zhao became a member of the Taiwanese boyband SpeXial and participated in the recording of their 4th album, Boyz on Fire. Along with several of his bandmates, he participated in the costume drama series Men with Sword.

On March 20, 2017, Zhao announced that he was going to leave SpeXial for unspecified reasons. His departure took place three days later, on March 23, less than a year after joining the group. He was also the second member to leave SpeXial after his bandmate Simon, who left the group on February 2, 2017. Zhao signed with Huace Media following his departure to embark on his acting activities.
