What is engraved on the door panel?

In ancient times, it refers to the inscription hanging under the eaves of the palace. In modern architecture, it refers to the inscription hanging on the door and under the eaves. Hanging a plaque, that is, hanging a signboard or various plaques, is a term in the old yellow calendar.

Plaques are usually hung above doors and under eaves. When there are doors on all sides of the building, plaques can be hung on all sides, but the front door must have plaques, such as royal gardens, temples and the residences of some celebrities. Many plaques are carved with dragons and phoenixes, flowers and patterns, and some are inlaid with pearls and jade, which are extremely gorgeous.
