You Miao is the son of the richest man, who grew up in a cute and pretty house. Once by mistake, he bought Li Zhifeng, a slave of Injun, for 200 taels to cure his illness and strengthen his body, and handed over the jade pendant he carried with him, hoping for his early recovery. From the moment he was rescued, Li Zhifeng decided to thank You Miao and to stay with him.
