As for the North Gate, in fact, "zai" rhymes with "zhi" (the gentleman in Feng Wang is in service). "The gentleman is in service, so he doesn't know his date, so Pierer". "the" department). The Book of Songs notes that "Wei" is a part of "Song", which rhymes with "He" and can also be used for reference.
The rhymes used in the pre-Qin period are quite different from those used in later generations, with obvious differences in dialects and the borrowing of useful rhymes. For example, the word "mother" is placed in the part of "fish" and "rain" in the wind, and the part of "zhi" and "qi" in Zheng Feng Neutron.
There is no uniform standard for rhyming methods in The Book of Songs, some are sentence by sentence, some are accidental, some are rhyming, some are rhyming, and some are rhyming. For example, hanbitsoft:
"There are trees in the south, so you can't think. There are wandering women in Han, so you can't think. The Hanshui River is so vast that it is impossible to cross it. Jiang Zhiyong, don't think about it. " Joe, Hugh, You, Autumn and Mu rhyme. At the end of the sentence, two more "thoughts" were put; The words "wide", "square", "swim" and "forever" are connected in the middle. The "one" and "four" at the end of the sentence rhyme.
Therefore, I am afraid that rhyming examples can only summarize the general nature, and specific poems need specific analysis.
