Is it better to learn modern poetry or ancient poetry? What should I see before learning from them?

It is better to learn ancient poetry first, because ancient poetry has many requirements and formats, so that you can understand the origin and changes of China's poetry culture, appreciate and understand the usage of words in poetry and the artistic conception expressed in poetry itself. As long as you know how to read, read and understand ancient poems, then modern poetry is a cinch. Modern poetry is straightforward, just highlight the artistic conception, and even rhyme can be omitted. Even if you know modern poetry, you are still one yard ahead of ancient poetry. It's like learning to drive. It's a bit awkward to learn to open the automatic gear manually at first, but it's a bit confusing to learn to open the automatic gear manually only.
