How to understand the "poetry method" discussed in "Canglang Poetry"?

"Poetry Method" mainly introduces the method of poetry creation. It is a discussion part in Yan Yu's "Canglang Poetry".

Original text:

To learn poetry, you must first eliminate five vulgarities: the first is vulgar style, the second is vulgar meaning, the third is vulgar sentences, the fourth is vulgar words, and the fifth is vulgar rhyme.

Rhymes do not have to have a source, and words do not have to be restricted to their origins.

It’s important to understand clearly and thoroughly, so don’t scratch your head. Speech is noble and free, don't be sloppy.

Rhythm poetry is more difficult than ancient poetry, quatrains are more difficult than eight-line quatrains, seven-character rhyme poetry is more difficult than five-character rhyme poetry, and five-character quatrains are more difficult than seven-character quatrains.

Only when you can tell the difference between a family and a person can you describe a poem.

There is no need to argue about the right and wrong of poetry. If you try to place your own poem among the poems of the ancients, and those who know it cannot tell the difference, it is really ancient.
