It seems that, across history, all the religions that prosper in China are non-theistic: Confucianism, taoism and buddhism, with only a few but notable exceptions like the Taiping Heavenly Kingdom

This seems weird to me because, as far as I know in the rest of the world theistic religions are the norm, even Japan which was super influenced by China developed Shintoism which is light on the "deity you must worship" but still has clear deities you are encouraged to worship

I know there are some clear deities people in China have worshiped, like the Heavenly Emperor or the Three Pure Ones but from what I've read they were never worshipped as universally or with the same devotion or reverence that gods in other religions have been worshipped. Worshiping them is just not very important

There's also the fact that while Buddhism developed in India it found a lot more success in China, probably precisely because it is a non-theistic religion

Why does this happen?, why does China seem to be THE place for non-theistic religions across history?
