Once inside the country, a Chinese visa can be extended for an extra 30 days for up to two separate occasions by visiting the Foreign Affairs Section of the Public Security Bureau. Extensions vary by price, depending on your nationality.
Expect to wait up to five days for your visa extension to be processed. You will also need to provide two passport photos. First-time extensions are generally easy to obtain. However, the second extension is much more difficult and will certainly involve a lot of luck and may only allow an extra week extension. The fine for overstaying your visa is officially 500 yuan ($75) per day.
All manner of lengthy extensions and conversions to different visa categories are widely available through agents for a fee. It is wise to carry your passport with you at all times because you will need it to register in hotels, buy airplane tickets or change money. If you lose your passport, you should report it immediately to your embassy, as well as to a Public Security Bureau near where you are staying. If staying any length of time, it is wise to apply for a residence permit from the local public security bureau.
