The panel of the square table is connected with a long leg and a short leg to form a rotating closed leg structure. This is more solid and stable. The square table is a common traditional furniture in China, and it is a specific square table. The four sides of the table are equal in length, and two people can sit on each side, and eight people can sit on each side, just like the square table nicknamed by the Han people.
