How to write rap in a different language?

specifically mandarin chinese because thats the language im learning to speak and write. i have noticed that lyrics in other languages, when translated to english, obviously doesn't rhyme in english, but also sounds pretty rubbish in the english translation, unless an english version is created. also every language has it's own culture, so as far as culture goes the style of writing will obviously be specific to fit the language. Also another thing is that the words used in the rap song/verse will have different rhyming words because they mean different and maybe even unassociated things in english. so how is it done?
