It's just that the picture has become rather muddled by the intermingling of folk religion with Confucianism, Buddhism, and Taoism over a long period of evolution and further complicated by the "encroachments" in more recent times of Christianity and Islam from the West.
只是經過長久的歷史演變，民俗宗教和儒、釋、道三種勢力互相交融，形成許多似是而非、錯綜複雜的關係，再加上近代西方的基督教、回收「入侵」中國，更使人對宗教興起「剪不斷、理還亂」的感慨。
