how do i get a visa? never done this before. is there anything i should know about safety etc?

Hi Janet! I'd like to give you some guidance. First, please prepare your passport, a photocopy of the passport's data page, a fully fulfilld application form affixed with your color bare-headed photo taken within six months, and round-trip tickets and hotel reservation copies. Then go to the CVASC in your residence district and submit the application.

As for safety, I think China is quite safe. Just remember to watch out your bags and not go out alone to places with few people there.
