保密

保密 means to keep something confidential or secret. It is commonly used in contexts where information must not be disclosed, such as in government, business, or personal matters.

The character 保 (bǎo) means 'to protect' or 'to guarantee,' while 密 (mì) means 'dense' or 'secret.' Together, they form a term that conveys the idea of protecting information from being revealed.

保密 is often used in formal settings, such as in legal documents, corporate environments, and official communications. It reflects the cultural value placed on privacy and discretion in Chinese society. The phrase can also be used in everyday conversation when someone wants to maintain secrecy about a matter.
