"Man Jiang Hong" can't be read in Mandarin. Why does it rhyme in Henan dialect and Shanxi dialect?

As for the rhyme of reading Man Jiang Hong in Henan dialect, I think it may be because Kaifeng and Luoyang in Henan province were the capitals of the Song Dynasty in history, so there may be some entering tones in Henan dialect. Of course, this is something that has not been academically demonstrated.

But objectively speaking, there is a considerable gap between Henan dialect and ancient pronunciation today. Yan Zhitui once said: "It is necessary to cover the past and the present, with the north and the south, the characters changed and the sounds changed. Therefore, it is awkward to read ancient works with today's voice. "

Angry, leaning against the railing, resting in the drizzle. Looking up, screaming in the sky, strong and fierce. Thirty fame, dust and earth, eight thousand miles of clouds and the moon. Don't be idle, grow old together and be unhappy! Jingkang is ashamed, but it is still snowing. When do courtiers hate their guts! Driving a long car, breaking through the lack of Helan Mountain. Eat pork when you are hungry, and drink Hun blood when you are thirsty. Stay from the beginning, clean up the old mountains and rivers, and go to the sky.

The rhyme of this epigraph is Lin 18, and the rhyme feet are: Xie, Jin, Yue, Qi, Xue, Jue, Que, Xue, queer vowel ie, ue. There is a simple reason. With the development of history, the pronunciation of Chinese is constantly changing.

Qin Shihuang only unified the writing method of the characters, but did not unify the pronunciation of the characters, so there were differences in dialects around the country. In Tang poetry and Song poetry, and later when people write poems, they often use Pingshui rhyme. Pingshui rhyme is said to be arranged according to the pronunciation of the Tang Dynasty.

Of course, if we read according to the ancient pronunciation, because there are no entering tones in Mandarin, it doesn't rhyme, and we can't even pronounce the rhyme correctly. Rush tone is a relatively short and urgent pronunciation.

The ancients summed up the pronunciation formula of flat and even tones: "If you are straight, you can prolong your life, and if you rise, you will rise." The sound fell like a falling stone, and it was short and urgent. "Because the rhyme of this word belongs to Rusheng word. Therefore, dialects that still retain the intonation, such as Cantonese, Wu dialect and Minnan dialect, will be more powerful to read and more in line with the style and rhyme of their poems.
