Xiao Shan is a famously profligate prince, the kind that makes his emperor father angry just by being seen. Xiao Shan’s greatest wish in life is to be a salted fish who lives without any worldly strife, until his father bestows upon him Xie Zhui, a ger who has been mixing with men, to be his bride.

Everyone says that Xiao Shan has married a ger who came out of a pile of men, with a vast grassland above his head. They think about how much the emperor must dislike Xiao Shan to have given him such a troublesome marriage.
