Blinds are a form of window that originated in China. In ancient Chinese architecture, there were straight windows, which were used from the Warring States to the Han Dynasty. The vertical strip is called the straight window, and the horizontal strip is called the lying window. The lying window is an original style of the blinds, and it can be said that it is the original state of the blinds.
Until the Tang Dynasty, the folks were represented by straight windows. In the Ming Dynasty, the lying window was greatly developed. In the Song Dynasty brick tower, a variety of various straight mullion windows were made. In the Ming Dynasty brick towers, there were also lying windows, and there were many examples. Those were the predecessors of the blinds.

The shutters and windows are slanted and can't be seen in the horizontal direction. Only the slopes can be seen. In ancient times, the wooden windows made by people used it mainly to achieve the purpose of ventilation and air circulation.
