Many of the issues pointed out here are worthy of discussion. As a work in progress like the rest of Wikipedia, this article will be improved with time. A big problem for articles about religion in China (and popular or folk religion in particular) is that this (extremely vast and varied) field of research has received little attention in the West until recent times and most of its literary heritage has not been translated in Western languages (or has been mistranslated). There are also discrepancies in the Western and Chinese understanding of what is and what is not "religious". Only recently Western and Chinese scholars are cooperating for a clearer analysis of Chinese folk (or popular) religion.
Regarding the style I have used in writing this article (for example the use of many notes, quotations, and the explanation of the different names of this religion or complex of religions), it is due to the complexity of the topic itself. I have partially taken inspiration from the article about "Hinduism".
Grammatical errors and bad structuration of some sentences are due to the fact that English is not my mother tongue. I apologise for this.
