Introduction to Hui Ran Hall: The back hall is the fourth entrance of the entire house, and the three rooms in the middle are "Hui Ran Hall". Huirantang is the place where the hostess of the Xue family meets relatives and friends and handles family affairs. It is also the place where the Xue family members gather together. Most of the beams in the back hall adopt the "round" technique, which is relatively simple. The partition screen door can be disassembled, making the space larger when major gatherings are held in this hall.
