The reason why there is no son-in-law on the cover of Tianxia is because Feng Huacheng is not the protagonist. Life on Earth is adapted from Liang's novel of the same name. This play is a photographic film set in the civilian community of a northern city. Tell the ups and downs of three brothers and sisters in Zhou family, Zhou, Zhou Bingkun and so on. Neither Feng Huacheng nor Cai is the protagonist of the story. Emphasis is placed on Zhou Rong's personal character. Will not appear on the cover of the family photo.
