China
China’s main draws that exceed other countries are:
1) the world’s richest breadth of culture,
2) the most varied and spectacular natural wonders, and
3) the most impressive architectural feats. With this size, and depth, and variety, in China you can see more in one place. As far as natural beauty goes, China goes bigger and more-varied and spectacular than any country in Asia (or the world if you count everything). Take for example Everest, the Yangtze gorges, the Taklamakan and Gobi deserts, Jiuzhaigou, Guilin, Zhangjiajie, Jilin’s Rime, and Hainan’s tropical beaches and forests.
