If you do go to China again, I suggest Jiuzhaigou National Park which is in Sichuan province (all seasons are nice but most breathtaking in autumn); Danxia Land Formation; Guilin Karst Mountains; the sights and landscapes along the whole silk road and many more. I can't list all the beautiful landscapes in China because there are simply too many which most people are not aware of (which I wish to go but I dont live in China, so it will take me a longer to tick off my bucket list). Non-chinese travellers just seem to know only the polluted cities of Beijing and Shanghai and dont really venture beyond where the gems of China are.
