开门

开门 (kāi mén) literally means 'to open the door' and is commonly used to describe the action of opening a door. It can also be used metaphorically, such as in phrases like 开门见山 (kāi mén jiàn shān), meaning 'to get straight to the point.'

The character 开 (kāi) originally meant 'to open' or 'to start,' while 门 (mén) means 'door.' Together, they form a compound verb that describes the physical action of opening a door or the figurative act of starting something.

开门 is widely used in daily life, from telling someone to open a door to using it in idiomatic expressions. It's an essential phrase for travelers and learners who want to communicate effectively in Chinese-speaking environments.
