I like couplets, but I can't speak Mandarin or Pinyin. Couplets are often uneven. Want to provide the fastest and most effective solution?

You don't necessarily know Mandarin. Classical poetry and even couplets. They are all based on the rhyme of Pingshui, and even the lines are based on the rhyme of Lin, not the rhyme of Mandarin. For example, in Putonghua, the word "white" is a rising tone and a flat tone, and the flat tone is an entering tone, which belongs to a falling tone. Of course, Mandarin is widely used now. When writing poetry couplets, you can also use new rhymes according to the pronunciation of Putonghua. However, you should know that the level off of ancient poetry couplets has nothing to do with Mandarin and Pinyin (of course, there was no Pinyin in ancient times). The ancients could do it without knowing Mandarin and Pinyin. Why can't modern people do it? ! Ancient people recite rhyme, while modern people recite rhyme. If you are a southerner, you will have an innate advantage, because some southern dialects still have tones (especially Cantonese) and Mandarin and northern dialects have no tones, so northerners need to recite rhymes (if they use horizontal rhymes) when writing ancient poems, while Cantonese only needs to be written according to their own dialects.
