Do you live in Sanlitun? Watch out, there are a lot of crazy, drunk, 605 drivers wandering around there...
IF you are FAA part 91, you can do recurrent and be all good. If you are 135 you will need a full initial if you haven't flown the type in over a year.
If you are in China, and have Chinese licensure, who knows? EASA? you'll need to start flight training all over again, and do it in French.
