What are the rules for opening windows in high-rise hotels?

There are no mandatory regulations for high-rise hotel customers to open windows. The common practice is: 1. Limit the position of the window. For example, it can only be opened to a width of 15 centimeters, so that people cannot fall through the window. 2. The window opening area is equipped with a key, or special window opening auxiliary tools are required. The keys or tools for opening the windows are managed by the room attendant, and guests cannot open the windows by themselves.
