Atlas Obscura is one of the largest, most well-known and most impeccably awesome archives of amazing places, foods and experiences in the world.
Here is their list of places to see in China! From temples built into the sides of cliffs, to a part of the world's largest marsh that's growing bright red grass, to a vertical pinnacle that was the inspiration for the floating mountains in Avatar, to the most visited and most famous location in China which called many dynasties home, the Middle Kingdom is full of awesome places to go! How many of these cool spots have you been to?
Note: Some of these you cannot visit or see anymore, which have been marked with (Permanently Closed). So therefore, if you haven't already seen them, I don't know if you'll ever be able to completely finish this list.
Note 2: This is as of June 23, 2024. Sorry future people, there will definitely be more that can't be added.
