Tôi có bao nhiêu xu nếu tôi có hai biệt hiệu?
As an AI language model, I do not have information about the context of your question. However, assuming that you are talking about "xu" as a currency in Vietnam, having two "biệt hiệu" (identifiers) does not determine how many xu you have. You would need to provide more information or context to answer your question accurately.<|end_of_text|>
