China officially the People’s Republic of China (PRC), is a sovereign state located in East Asia. It is the world’s most populous country, with a population of over 1.35 billion.
Most of the people will arrive in China via Beijing or Hong Kong. Shanghai is also a possibility from western countries. More cities can off course be reached from Asian countries…
Of all the above, Hong Kong is probably the best choice as you can get the cheapest and longest visa there, it is not too far from the favorite backpackers’ areas, it is itself very interesting and it will give you a transitional period before the real adventure… Also, plane tickets tend to be slightly cheaper to HK than to Beijing.
