First of all, poems must rhyme, but rhymes do not change. The last word of the 2468 lines must have the same rhyme and must be flat (that is, it must have one or two tones). "Qing" and "心" barely have the same rhyme, but "wen" and "Xian" are quite different.
Secondly, the second and third couplets of the rhymed poems need to be in opposition, not only in meaning and structure, but also in pronunciation. There is no opposition between your chin couplet and your neck couplet.
As for the level and level, haha, this is more difficult to explain. Generally, there are four types of leveling and leveling modes of Wulu. The level and level of each character has very strict requirements, but if it is a good sentence, there can be appropriate Changes, but if there are too many flat or oblique sounds in a sentence, it needs to be remedied, which is more troublesome in detail. However, the requirements for flat and oblique sounds in ancient poetry are not very high now. After all, this is too difficult. hehe!
By the way, there are only forty characters in Wulu Yi***. Generally speaking, it is best not to have repeated words, otherwise it will give people a feeling of low level.
Poetry expresses ambition, at least this is good. Nowadays, fewer and fewer people like poetry, and fewer and fewer people write poetry. It’s already good that you can write it. If you really like it, read more poems. Not only read the content of the poems, but also look at the structure and format. You will be able to improve.
