Chinese Phrase: I'm sorry
Dui bu qi (Face not up).
This can be used in two situations. You can say it when you have to get someone's attention or to bother the person in some way - for instance, when you need to have one step aside so that you can pass through. Used in this situation, "Dui bu qi" is the English equivalent of "Excuse me." The phrase can also be used when you actually apologize - for instance, when you have failed to arrive on time for an appointment and have kept the other party waiting for you.
