What did ancient doors mean in the past? What's the point?

The longer people grow, the more they have a soft spot for ancient things. Today, what do the ancients mean by the design of doors?

In ancient buildings, most doors are made of wood. Generally, doors have abutments and pay attention to axial symmetry. There are cymbals and knockers on the main door, and two wooden pegs on the back. I used to hear the old man say that the door can only be entered at the second door. I don't know what that means. Now I understand that there were several doors in ancient people's doors.

First of all, there should be no puddle or pool in front of the gate and no water in the west. The ancients thought that there was water in front of the door just like the door was crying, and there could be no water in the west, because the direction in the west was square and there could be no trees facing it.

Then there is the threshold, which can keep out the rain and prevent some mice from running in. If you step on the threshold in someone else's house, it will be considered rude. In the past, the threshold also reflected the social class.

The decoration of the door should be simple and avoid painting and carving. It is generally understood that the gate of the yard is not suitable for heavy makeup, but for simplicity and simplicity, without too much decoration. Usually only the gate of the temple is painted.

If someone's door painting will be understood as like a temple, it is not a praise tone, it means a curse, and it is also a taboo among the people.

The ancients knew the door very well.

Wen Zhenheng, a scholar in the late Ming Dynasty, wrote in "Chronicles of the Long Story": "The knocker has the face of an ancient butterfly, or it is a gluttonous one. It is best to nail it on it, or use red copper or fine iron, such as old-fashioned casting, yellow and white copper are not available. The paint is only red, purple and black, and the rest are not. "

Door knockers/cymbals The ancient imperial court had a very clear hierarchy for the door knockers of residential houses. "Ming History" records: "The main entrance of the four cities of Prince Mi is painted with gold nails and copper rings; Green oil copper ring at the entrance of Gongwangfu; Gold lacquer animal face tin ring for the back door of Guanbai No.1 Middle Palace; Black oil tin ring of three to five official doors; Six products to nine products official door black oil iron ring.

In ancient times, the homes of ordinary people were two doors, and large families opened four doors. The so-called big family refers to rich officials and businessmen, who generally live in quadrangles.

The ancient yamen opened six more doors, showing majesty and style. Later, six doors were used to refer to the government and yamen.

In short, the ancients attached great importance to doors and paid great attention to details. Very particular.
