Mian Mian, a Taoist boy in Langya Mountain, is actually the lost daughter of Jin King Li Jinhan. She is extremely talented, sinister and clever. She went down the mountain to find her father, but was betrayed by a Taoist boy who stole a jade pendant and pretended to be her father. Mianmian relied on Taoism to prove her identity and settled in Prince Jin's Mansion. While curing Li Jinhan's leg disease, she helped him resolve evil spirits and conspiracy. She outsmarts the fake emperor Li Xiao who covets the throne, and the concubine West who feeds evil spirits, and reveals the truth about "a civet cat for a prince". With the help of the Supreme Emperor, the Queen Mother, and their master, Taoist Master Miu Wu, the father and daughter worked together to defeat the rebel conspiracy. Li Jinhan returned to the throne, and Mian Mian was canonized as the Crown Princess, and together they protected the peace of the family and the country.
