From Liu Chenxi, an upright and kind doctor in One Servant and Two Masters, to Yang Shu, a kind driver in One Servant and Two Masters, to Wang Guilin, an upright and kind factory director in Floating and Sinking, Zhang Jiayi's image of a "good man" is deeply rooted in people's hearts. This spring, he returned to the screen with the TV series "The Return of His Ex-wife", and once again interpreted the "pure man" Li Guosheng who attached great importance to emotion and righteousness.
