In architecture, a window refers to an opening built on a wall or roof to let light or air into a room. In fact, the original meaning of window and door refers to window and door respectively, while in modern Chinese, window only refers to window.
"Window" was originally called "chimney" ("chimney" is a common word), that is, a hole is left in the wall, and the window lattice in the frame can transmit light or smoke, and the prefix "hole" is added to form pictophonetic characters.
