TAOISM
China is popularly supposed to have three religions,—Confucianism, Buddhism, and Taoism.
The first is not, and never has been, a religion, being nothing more than a system of social and political morality; the second is indeed a religion, but an alien religion; only the last, and the least known, is of native growth.
The Chinese themselves get over the verbal difficulty by calling these the Three Doctrines.
There have been, at various epochs, other religions in China, and some still remain; the above, however, is the classification commonly in use, all other religions having been regarded up to recent times as devoid of spiritual importance.
Mahommedanism appeared in China in 628 A.D., and is there to this day, having more than once threatened the stability of the Empire.
In 631 the Nestorian Christians arrived, to become later on a flourishing sect, though all trace of them, beyond their famous Tablet, has long since vanished.
