来信

来信 means 'incoming letter' or 'letter received.' It specifically refers to a letter that has been sent to someone, emphasizing the act of receiving rather than sending.

来 (lái) means 'to come' or 'arrive,' and 信 (xìn) means 'letter' or 'message.' Together, they form a compound noun that describes a letter that has arrived at its destination.

来信 is commonly used in formal and informal contexts, such as in business communications or personal correspondence. In Chinese culture, letters were historically an important means of communication, and the term still carries a sense of tradition and personal connection.
