As per mentioned before, Buddhism did not originate from China, thus it was seen as something foreign. And in the history of Buddhism, because of this fact, it has been clamped down hard by leaders with political agenda. The actions taken against the religion and people who practise them were as extreme as Qin Shi Huang burning books.

The Chinese words which we are using now, if their origins cannot be explained, it is most probably a wrongly written word in the past when people copy books to be passed around and down. Well, this can be a classic case of wrong being right when it has been used long enough. ;)

The myths and legends which we read now may seem nonsensical and illogical to us. But when they were come up with, it is with the sole purpose of explaining how things are happening around when science is still very far from developed. Through understanding the stories, we can actually get a sneak peak on how our far far far away ancestors used to think, it can be pretty interesting. :P
