Cultural tips
In China, asking how much for something is often the focal point of conversations. "How much did the watch you're wearing cost?" "How much is your rent?" "What's the price for the apples you bought?" Please don't be surprised when you hear this kind of questions. You can always dodge the question by saying, "我忘记了。wo3 wang4 ji4 le.", ("I forgot") or "我不知道。wo3 bu4 zhi1 dao." ("I don't know") if you feel uncomfortable with it.
