China has long belonged to "folk" religion. It's not that people couldn't organize in the past; it's just that Confucian rationality and humanism had a grip on the elite, and other religions couldn't get a foothold.
中國自古以來就是屬於「擴散性的宗教」，這倒不是祖先們沒有組織能力，而是儒家「理性思想」、「人本思想」太根深柢固，控制了整個官僚體系和知識界，使得其他的宗教哲學始終出不了頭、難以「坐大」。
