The difference between a door and a door

the difference between a door and a door lies in their different structures and uses. A door is a traditional China door, which usually consists of two or more door leaves. It can be opened or closed to separate indoor and outdoor, different rooms or different areas. A door is a separate door leaf, usually made of wood, metal or other materials, which can be opened or closed for entering or leaving a room or building. Therefore, a door is usually used in large buildings or traditional Chinese buildings, while a door is more common in modern buildings and families.
