"I hope that the world will be beautiful beautiful of you." is not a correct statement. I'm not sure what you want to say, but it sounds like you want to say that "I hope that the world will be beautiful for you." If I have misunderstood, send the sentence in the original language and I'll see what I can do.

Yes, there is something wrong with the sentence. You could say " I hope the world will be as beautiful as you are."

First of all, your first question should de written like this: "Is there anything wrong with this sentence?" Then, your sentence is very confusing. To call a person beautiful means they are physically attractive, or very caring and generous with others.... you could say: "I wish the world was as beautiful as you are." This is the basic structure of a metaphor, using the conjuction "as."

Actually, I used google translator in order to understand your intent exactly... I guess you wanted to say "I hope that the world will become more beautiful because of you". 'Does this sentence have anything wrong?' or easily 'Is it wrong?'
