An ancient "harmonic rhyme" format is also called "step rhyme". It requires the author to use the original rhyme and original words of the poem being harmonized, and the order is the same as that of the poem being harmonized. and one of the most restrictive in poetry. For example, Huang Luzhi's "The Second Wang Dingguo Yangzhou Sees the Mail": "Qingluo misses you day and night. When will the sails be gathered when you return to the north? Your hair is not white yet, but you can still drink wine, and the blue clouds hang down, but you live in the state. The flying snow drives the plate to beat the belly of the fish, Mingzhu talks about fighting with boiled chicken heads. It is not a bad thing to have fun in life, how can there be sorrow in Zhuxi's songs? "
As for the beginning of the second rhyme poem, there are scholars who said it began with Yuan Zhen and Bai Juyi in the Tang Dynasty. For example, Cheng Dachang of the Song Dynasty said in "Archaeological Compilation: Rhyme of Ancient Poems": "The second rhyme in the Tang Dynasty originated from Yuan Weizhi and Bai Letian." Zhang Biaochen's "Coral Hook Poetry Talk" said more specifically: "Predecessors did not begin to harmonize rhyme when they wrote poems. . Since Bai Letian was the governor of Hangzhou in the Tang Dynasty, and Wei Zhi was an observer in eastern Zhejiang, he kept a mailbox to promote peace, and he started to follow this view. In modern times, Chen Shengcong's "Jianyu Ge Poetry Talk" still said: "Poetry secondary rhymes began in Yuan, Bai, Pi, and Lu in the Tang Dynasty, and flourished in Su and Huang in the Song Dynasty." Mr. Bian Xiaoxuan's "Tang Dynasty secondary rhyme poems" was Yuan Zhen's first research "The research further proves that the secondary rhyme poems were originated by Yuan Zhen, and it was said that the creation date was the fifth year of Yuanhe (810). The original poems were five poems including "Huai Le Tian Shu Huai Jian Ji" written by Yuan Zhen in Jiangling Prefecture.
In fact, before the Yuan Dynasty and the Bai Dynasty, Lu Lun and Li Yi, among the ten talented men in the Dali calendar, had a mutually beneficial relationship. Li Yiyou's poem "Gift to Brother-in-law Lu Lun": "We are worldly and middle-aged, and we will be together for the rest of our lives. But sorrow and illness will come to Lang Lingweng." ("Full Tang Poems" Volume 283) Lu Lunhe's poem "Reward" "Li Yi Duangong's Night Banquet Sees a Gift" is: "Qi Qi and Xi Dong, ten years ago, they are the same. It's a pity that the singing and drinking night is relatively weak." ("Full Tang Poems" Volume 277)
According to Mr. Fu Xuancong "Lulun Kao", Lu Lun died in the 14th and 15th years of Zhenyuan (798, 799), "Reward for Li Yiduan at the Night Banquet" was written in Zhenyuan, which shows the secondary rhyme in Chinese classical poetry The style appeared in the Zhenyuan period at the latest, so it cannot be said that sub-rhyme poetry originated from the Yuan and Bai Dynasties, let alone Yuan Zhen.
