How was the ancient homestead divided into one entrance, two entrances and three entrances?

There are several rows before and after the house in the ancient bungalow, and each row is called an entrance. Enter, that is, the level of the old house.

The shape of "mouth" is called courtyard; The shape of "sky" is called binary courtyard; The shape of "wood" is called Sanjinyuan. Among them, the courtyard of Sanjin Courtyard was the most standard courtyard structure in Ming and Qing Dynasties, with the most reasonable and compact layout, which was widely used by the people.

2. A main courtyard and a parallel courtyard.

If a row of houses and a yard are added to the east or west of an independent courtyard, it will become a main and disposable parallel courtyard.

3. Two or more groups of parallel courtyards

Two groups of parallel courtyards are formed by juxtaposing two courtyards of equal or similar size. This is the form a wealthy family's house takes.

In a big family in feudal society, two brothers lived together. In this way, when building a house, two houses are often built, one for each brother. The size and pattern of the two houses are the same or similar, and they are independent and communicate with each other. This is one reason for the emergence of two groups of parallel houses, and of course there are many other reasons.
