China (63 million)
China is the world’s fourth most visited country. It seems to be like that as the country is large and has many connections to other Asian countries.
You can experience different kinds of historic cities such as Beijing, modern cities as Shanghai, or you can simply just see sights such as the Great Wall of China or go ahead the mountains.
Many tourists think that there are many opportunities and no matter what part of China you visit, you will be impressed.
Airline tickets are expensive, and that is the biggest problem for travelers.
