Introduction to the sedan hall: The sedan hall is the first building on the central axis of Mo's Manor. It is a place where the host greets guests, sees off guests, and stops the sedan to prepare tea, so it is also called a tea hall. The large green cloth sedan displayed in the hall is an official sedan for a third-rank official, and the other rattan sedan is a casual sedan. The black-tiled white wall facing north in the courtyard has the Chinese character "Hongxi" written in Yang. This wall is commonly known as the screen wall or the screen wall. It was also called the screen in ancient times because it stands opposite the main hall, the center of feudal ceremonial activities. Guests walk through this wall. The wall and the owner began to meet each other to show respect. In ancient Chinese, "xiao" and "su" were connected, so the wall was also called Xiao wall.
