出入

The Chinese word 出入 (chūrù) is composed of two characters: 出 (chū) and 入 (rù). The character 出 originally meant "to go out" or "to leave", and it is often used in the sense of "to exit" or "to depart". The character 入 originally meant "to enter" or "to come in", and it is often used in the sense of "to enter" or "to arrive". When these two characters are combined, they form the word 出入, which means "to go in and out" or "to enter and leave". This word can be used in a variety of contexts, such as to describe the movement of people or objects, or to refer to the process of entering and leaving a place. For example, the sentence 他每天都出入图书馆 (tā měitiān dōu chūrù túshūguǎn) means "He goes to the library every day".
