Appropriate
Avoid when
You can say 不用谢 (búyòng xiè), which literally means 'no need to thank me'. It is a common and polite response to thanks.
It is pronounced búyòng xiè. Note that 不 is pronounced with the second tone because it comes before a fourth-tone syllable.
Both are polite responses to thanks. 不用谢 is slightly more modest, while 不客气 is a bit more formal. You can use either in most situations.
