Only kindness and virtue can be used as doorplates. Good virtue is a sentence that imitates the inscription in the humble room: good virtue is the only one. Wei Wu Dexin: It's just that I (the person who bought the house) have a high moral character (so I don't feel humble). Just, I: I, here refers to the person who gives himself a house. Xin: Aroma, here refers to noble character. As a symbol of national culture, plaques have been widely used in cities and villages. Due to historical changes and other factors, it is difficult to see old plaques with cultural relics in cities now.

The more common plaques can be roughly divided into five categories according to their nature: one is the hall number plaque, such as Yuewei Caotang in Ji Xiaolan; A kind of memorial archway plaque, which is usually used as a commendation, such as commending the rich for observing norms and commending rural teachers; One kind is birthday celebration, and there are a lot of such plaques; First, famous plaques in developed commercial areas, such as Rong Baozhai and Tong Ren Tang. The other is the inscription plaque of literati, which is literary or aphoristic. At present, the inscriptions, shop names and mottos of literati are popular. The historical plaque was the first cultural relic to be destroyed. Because it was hung in the open air, it is rare to see old plaques in cities at present.
