What are the differences between Russian poetry and our common modern poetry in China?

The landlord's question is vague, too general and too extensive. I can't explain your question clearly in a paper, so I just found some information for you:

In linguistics, the existence and generation of poetry involves at least five relationships: (1) phonological relationship; (2) semantic relations; (3) Grammatical relations; (4) Rhetorical relations; (5) Cultural relations.

(1) Phonetic relationship involves the relationship between rhythm, prosody and tonality of poetry. For example, alliteration, homophonic rhyme, iambic, iambic, four-step, five-step and six-step in Russian poetry have certain influence on the generation of poetic meaning. China's poems pay attention to the levelness, rhyme, intonation and musicality of Russian and China's poems.

Is it a big head, so I really can't answer your question. However, I suggest you read this book, A Linguistic Study of Poetic Generation.
