A Few Questions about the Ancient Chinese Anti-Cutting Zhuyin Method

"Ye yin" is a method used by the Song people to temporarily change the pronunciation of a certain character to ensure the harmony of the poem. Not realizing that the Chinese language had changed a lot from the pre-Qin Dynasty to the Song Dynasty, and realizing that the rhyming characters of the Book of Songs or other rhyming styles no longer appeared to be in harmony at that time, the Songs believed that the pre-Qin Dynasty people temporarily rephrased some of these characters to sound like something else when they used them. The word "葉此履反" means that in Zhu Xi's understanding of phonetics, the word "采" was not pronounced as "取", but in order to harmonize the sound and rhyme, it was temporarily repronounced as "take". "去逆反，叶去略反" should mean that the character "綌" was pronounced as "弃" in the Song Dynasty, but here it was temporarily rephrased as "却" for the sake of harmonizing the rhyme.

It seems that "mother" should be pronounced "某", and the word "后" has two cuts in Guangyun, one is upward and the other is downward. To harmonize with the word "no" here, it should be taken as the upper tone.

If we go by the ancient tone, we can say that the tone of the character "下" depends on the tone of the character "下". If the modern Mandarin pronunciation to read the opposite cut, the tone does not depend entirely on the tone of the next word, but also with the upper part of the vowel of the clear and cloudy have a relationship. A few common rules are: qingping is yinping, and turbidping is yangping. (Before Song Dynasty, there was no yinping and yangping. Assuming that a character's backward cut is a ping sound, if the upper character's vowel is clear, it is yinping in Mandarin, and if the upper character's vowel is turbid, it is yangping in Mandarin. (There is a typical example: dong, de hongche - the consonant of hong is ping, the consonant of de is tuan, clear, so "dong" is not yangping in modern Mandarin, but yinping.) Turbid upper changes to go, all turbid entries change to yangping, and the second turbid entries change to go.

The subtleties of the reverse cuts are very complex and need to be learned carefully. If you are really interested, we recommend you to buy some books on phonetics and read them, and ask Chinese students who have studied phonetics.
