Dear Wang Ping，
I’m very glad to have received a letter you sent me two weeks before．I’ve been thinking about the question you ask me．In my opinion，you should come back after you finish your studies at abroad．For one reason，what you are studying is bad needed nowadays in China．It will be quite easy of you to find a good job．In fact，I know that a few big company in our city are hoping to hire people like you．For other reason，I think it will be much more convenient for you to look after your parents as we are getting old．Therefore，I think it’s a good idea for you to return．So what are you waiting?
Best wishes．
Yours，
Li Hua
