How to check the phonological state of a word in Guang Yun?

You can refer to Lectures on Chinese Phonology, edited by Ding Shengshu, compiled by Li Rong, and published by Shanghai Education Press 1984 and 16, but it is only 34 pages.

This paper lists in detail the methods to deduce the sound of "Guang Yun" according to the current sound.

In ancient times, nothing was more refined and useful than phonology.

There is a simple way to remember the voice state.

Construct it yourself, try to distinguish all opposites with the least meta-auxiliary system (dialect materials can be ignored for phonology majors), and then start reading poems with this system.

You have finished reading 300 Tang poems, and you have basically memorized them. But notice that half of the words are polyphonic, and pay attention to "four sounds with different meanings".

There is no good way, we can only do it one by one. You can try to use dialects to investigate the vocabulary. Phonetic symbols can be used to determine the attribution of sixteen beats, but they are of little help to specific rhymes and initials.
