The book "Shan Hai Jing" was written in an unknown time, and many pronunciations have local dialects, which can't be found in the dictionary. You can describe this area according to it. Apply the local dialect in two aspects:

First, in the process of book circulation, due to various factors, some words are added or subtracted from another word, which is unusual.

Secondly, in the development of Chinese characters, especially in the last hundred years, due to the explosive growth of knowledge, in order to absorb more knowledge, many characters have been simplified into homographs, so that the characters before simplification (especially variant characters) are not recognized.
