What's the name of the plaque with the surname on it?

Doorways painted with surnames are generally called "painted surname plaques" or "painted surname plaques". In the traditional culture of China, the surname plaque is a common family logo, which is used to show the family's identity and status.

Generally speaking, Tu's family name will be engraved on the door plaque, and other family symbols, family precepts or ancestral precepts may be attached to show Tu's family honor and values. However, it is worth noting that due to the diversity of surnames, house numbers painted with surnames in different places may have different names and styles. Therefore, under the specific geographical and historical background, the names of house numbers painted with surnames may be different.
