The so-called sign is a square wood or log embedded in the lintel, commonly known as the door bolt. If it's a stone, the sign material is also painted with oil paints or pictures according to the grade, or written with greetings such as good luck and longevity. These are the highlights of status. The well-known word "according to the lintel" is actually an intuitive expression of people's yearning for power and wealth.

Door head generally refers to the location of the facade of a building, such as the gate of a shopping mall, the facade of an enterprise, the entrance of a villa, etc. Located under the lintel, it covers an area larger than the lintel and can be opened and closed. People will decorate it with doorframes and doors. However, there is still a big difference between the lintel and the door head. Intuitively, the door head can be opened and the lintel can only be fixed on it.
