Zhao Liying was asked in an interview before: "How many points do you give yourself in Chu Qiao Biography?" And Zhao's answer is: only nine points, because only half of it is shown.
It is reported that Zhao lost eight pounds for the role of Chu Qiao, but he is not fat at all, so this is one of the reasons why Chu Qiao Biography has been waiting for Zhao for three years, which is inseparable from Zhao's Excellence and hard work.
