Which episode of the TV series "Old Nine Men's Yin Xin Yue" appeared? Why do you want to marry Yin?

I remember it was about 10 episode. In order to treat February Red's wife, Zhang Qishan needs to go to the auction of Crescent Hotel to buy a Chinese medicine, but Zhang Qishan has no invitation to the Crescent Hotel. Without an invitation, he can't enter the Crescent Hotel. So Jiuye thought of a way to get an invitation from a man named Yin, who turned out to be Yin's fiance and the invitation was sent by Yin's father. Zhang Qishan accepted the invitation and went to the Crescent Hotel as Sanbian Peng. Yin also fell in love by mistake. Later, knowing that he was not Sanbian Peng, he decided to follow him to Changsha. Later, I fell in love with Yin and got married.
