Ancient luxury houses often have three entrances and four entrances. What's it like?

Many people watch ancient TV dramas and hear lines saying that the ancient houses are like this: one enters, two enters, and three enters. So what exactly does this mean? Maybe at first, many people, like me, didn't know what it was. Later, it was found that gold was actually the unit of measurement of ancient houses.

Just as our current unit of weight is Jin and kg, there are also units of measurement for houses in ancient times. Only this unit of measurement is called "inch". In fact, an entrance means a hall. If there are three entrances, there are three halls with seven or eight houses. Generally, a three-story house will be divided into three parts: front hall, middle hall and back hall. If it is a four-in, there will be a slant hall.

In ancient times, the size of the house indicated whether the family was a wealthy family. So in ancient times, many people like to make their homes as big as possible, which also shows that people at that time had this concept of real estate. Like Sanjin, it is actually composed of the main hall and the front and rear halls. Generally, the most vocal people in this family live in rooms on both sides of the main hall. The two rooms on both sides of the main hall will be called wing rooms, usually where the owner and his immediate children live. Well, if it's a house with a slant hall like Jin Si, if it's a big family, it may be where many maids live. If there is no maid replacement at home, it is usually to provide accommodation for guests from afar.

Having said that, in fact, to sum up, progress is only a unit of measurement.
