Introduction to the middle-aged residence: When people are middle-aged, there are old people at the top and young people at the bottom. The atmosphere of life is relatively strong, and the furnishings are relatively simple. On the left is the top bed used by middle-aged couples, and the one on the right is called the "Arhat Bed." The owner could chat and play chess on it, but after opium was introduced to my country in the Qing Dynasty, the Arhat bed was transformed into a smoking couch. This painting in the middle hall is Guan Gong's "Reading the Spring and Autumn Period at Night". It can be seen that Guan Gong's righteousness echoes the word "virtue" on Luohan's bed. It can be seen that the Kang family educates their children with "virtue" and "righteousness".
