Emperor Zhengde Zhu Houzhao (played by Richie Jen) grew up in the deep palace. Although there is a "common people's street" where eunuchs and palace maids play various characters for him to play the game of "pretending to visit incognito", Zhengde has long been tired of the fake performance. So he took the opportunity of the Queen Mother to arrange a wedding for him and went out of the palace with historian Sima Xi (played by Law Kar-ying), commander Chen Zhenzhen (played by Liang Xiaolong) and the imperial physician.
