The fire window of Evergrande's fine decoration could not be opened.

The reason why Evergrande's finely decorated fire windows can't be opened is because they are usually fixed fire windows without opening fans. The movable fire window is equipped with an openable fan and a sash switch control device, which has the function of manual switch, and at least has the function of automatically controlling the closing of heat-sensitive elements such as fusible alloy or glass balls.
