It's okay. Douban says that Yin Zhenheng and Zhou Ru are characters in "Dark Glory". Zhou Ru is a plastic surgeon, an admirer of Wen Dongen, and one of the roles to help her get revenge. Yin Zhenhuan is the old man crying for coffee in the play. Zhou Ruzheng has nothing to do with Yin Zhenhuan. "Dark Glory" is a TV series produced, directed by He Anqi and written by Song Hui, Li, Ji-yeon Im and Zheng Xingyi.
