      Shutters are a style of windows, which originated in China. In ancient Chinese architecture, there were lattice windows, which were used in various dynasties from the Warring States period to the Han Dynasty. Straight bars, straight latticed windows and horizontal bars, are called window frames. The original style of the louvered window or shutters is also the original state of the shutters.
       
      By the Ming Dynasty, the window of the lie lattice had been greatly developed. In the Song Dynasty brick pagoda made a variety of straight-framed windows, in the Ming Dynasty brick pagoda also made sleeping-framed windows, especially many examples, that is, the predecessor of shutters. The Venetian Louver Atlas (1) (20) is actually a window lattice, mainly used for ventilation and exchange of fresh air, as for the window lattice, of course, no more than a few patterns, either horizontal or vertical, then the horizontal is the rudiment of the Venetian louver. Strictly speaking, the latter is different from the louver in that the latter is horizontal and transparent. The louver window lattice is made of oblique lattices, which can not be seen horizontally, but only by oblique view. Such
