[0002] Venetian blinds are a style of window that originated in China. In ancient Chinese architecture, there were mullion windows, which were used in various dynasties from the Warring States Period to the Han Dynasty. The vertical bars are called mullion windows, and the horizontal bars are called horizontal mullion windows. The horizontal mullion windows are the original style of Venetian blinds, or it can be said that it is the original state of Venetian blinds. Compared with curtains, the flexibly adjustable blades of Venetian blinds have functions that curtains lack. In terms of sunshade, in addition to blocking ultraviolet radiation, Venetian blinds can also adjust indoor light.
