Dear Prof. Smith,
I am Li Hua, a high school student from China. I am trying to decide on what major I will study at university, and writing in the hope that you can guide me in my options.
I discovered your area of research while examining my options on the Internet. I found your subject area to be of particular interest to myself. If possible, could you please provide me with some further information regarding the procedure? Could you also advise on the required qualifications for this course?
As this is an important opportunity, I am extremely keen to have the strongest application. Any advice on strengthening my application would be greatly appreciated. （107words）
I am looking forward to hearing from you.
Yours,
Li Hua
