I’m very glad to have received the letter you sent me two weeks before. I have been thought about the question raised in your letter. In my opinion, you should go back after you finish your studies at abroad. For one thing, that you are studying is badly needed nowadays in our country. It will be quite easily for you to find a good job. In fact, I know that a few big company in our city hope to hire people like you. For another, I think it will be more convenient for you look after your parents because they are getting older and older. And this is only my point of view. It is up to me to make a right choice.
