Yinping is a beautiful woman born in East Arowana. There is a deep rooted belief that females have less value than males, yet she tries her hardest as the first born to make her father proud. However, her father always drinks and never stops complaining about her gender, reaffirming the fact that he wanted a son instead of a daughter.

Yinping and her little sister Bingbing run the family store with their father, selling plant seeds, tea, wine, and kitchenware. The Bureau of the Royal Household is no stranger to ordering wine and tea from the store, garnering much interest and many customers. Sullivan, interested in her intelligence and diligence, visits her from time to time. She will marry Sullivan and move into the castle with him, leaving Bingbing to run the store in her stead.
