Entry
Hong Kong belongs to China as a Special Administrative Region and sets immigration rules of its own, and separate permission is needed to enter mainland China. Whether a visa is required depends on the passport; the Immigration Department's page lists who needs one and the permitted length of stay. Guides give differing validity periods, from 1 to 6 months after the stay ends, so aim for 6 months at least. A return or onward ticket is something airlines often ask to see. On the Immigration Department site, look up whether a pre-arrival registration or arrival form may apply to your passport.
