简介：Fuchuan House is both a wine shop and a tea house. It has three floors: a wine shop on the first floor, a teahouse on the second floor, and a private room for distinguished guests on the third floor. Originally, there were two tables of guests in the private room on the third floor, but Tian Shouxin took them away. When Zhu Cixiang went up to the third floor, there was only one table of them on the third floor.
