Couple small translation questions Hey guys, At this very moment I am studying Chinese but there are some things that confuses me. Hopefully you can help out! 1st confusion 您好，我想换800元现金还信用卡. 换人民币还是换美元？ ……。 The sentence confuses me. It doesn't make sense: I want to change 800 yuan cash also credit card. My best guess is that someone wants to put 800 cash on their credit card? What is the correct translation? 2nd confusion How do I write down 10020? 一千00二十 or 一千0二十。 So basically 1 or 2 times a 0? 谢谢你们！
