Dear Wang Lei,
I know from your letter that you are upset about the relationship between you and your parents.I can understand how you feel. (写信目的)
When I was young,I had the same experience as you do. 【高分句型一】But after I talked to my parents heart to heart,we had a better understanding of each other.(简述自己类似的经历) So try to communicate with your parents to let them know that you are wise enough to manage your own business well.To understand them better,you should always put yourself in their position.Don't you think that all parents in the world love their children even though they are sometimes strict and serious?If you can spend your time and money wisely,I am sure that your parents will trust you and you will enjoy more freedom.By the way,it's understandable that your parents ask you to put your studies in the first place. 【高分句型二】(提出至少两条建议)
I hope my advice is of some help to you. (希望)
Yours,
Li Hua
