hi,nice to meet u!
to start with, you shouldn't write"爱西"in this sentence,by that i mean,"ai4xi1--爱惜" means you take good care of sth,more precisely, "ai4xi1"is acceptable in other conditions,like"i will take care of the outfits which you give me on my birthday."--"wo3我hui4会ai4爱xi1惜ni3你zai4在wo3我sheng1生ri4日na4那tian1天song4送wo3我de1的yi1衣fu2服de1的。"overall,you shold put "xi3huan1喜欢" or "ai4爱"in this sentence--你最喜欢/爱的诗是什么?为什么?hope I can help you something in chinese :)
