Canceling an Uber is quite easy to do with little Chinese, as the app is in English.
I've tried to cancel a didi before but was stymied by my reading inability in Chinese. Would it be possible to show an updated "How to use Didi" for those like me?
My friend told me about the wonderful "I'm where the pin says" option to select as soon as you have a driver, but I want to know how to cancel if the driver shows up with the wrong plate number, as has happened before with didi AND didi-taxi.
