Why did xiguan big house design the form of the gate?

The door is an ancient "security door", which can be opened left and right to ensure ventilation and basic safety.

The gate of xiguan big house consists of three doors. The first is the screen door, which is like a pair of window sashes, blocking the view of passers-by outside. This road is light and easy to open and close. The third door is a real door, not special. Most old buildings have this kind of door. The most distinctive is the second door, called the trip door. The whole thing looks like a big wooden frame with more than a dozen pieces of wood across it. The curator emphasized that this log must be singular, not even, because in Cantonese, "double" and "mourning" are homophonic and unlucky.

The weather in Lingnan area is hot and humid, so pay attention to ventilation in houses. Screen doors and step-in doors play this role. In the traditional residence of Chaozhou, the small family has two doors. The first door is the combination of screen door and trip door. That is, vertical logs are inserted at intervals of more than ten centimeters above the screen door, which seems to be called a railing door. This door is usually closed when there are people at home during the day.
