What are you trying to say? It still doesn't make sense. If we can formulate your sentence, then Mr. Matthews will be better able to answer your queries.
" Happy birth day a person...
" Happy birthday to a person...
who lives of half of the
world " .
Do you mean to write: "...who lives off..." ?
What is this person doing? Can you write "...who lives of/off half of the world" in different words.
