In Chinese, the word for "no" depends on the context, but the most common ways to say "no" are:

• 不 (bù) - This is the general negation word meaning "not" or "no." For example:
  • 不要 (bù yào) - "Don't want" or "No, thank you."
  • 不是 (bù shì) - "Is not" or "No."
• 没有 (méi yǒu) - Means "do not have" or "there is not," often used to say "no" in response to questions about possession or experience.
• 不要 (bù yào) - Specifically means "do not want," often used to refuse something politely.

If you want to say "No" as a simple refusal, 不 (bù) or 不要 (bù yào) are commonly used.

Example:

• Q: 你要咖啡吗？(Nǐ yào kāfēi ma?) - Do you want coffee?
• A: 不，谢谢。(Bù, xièxiè.) - No, thank you.
