Dear Robert,
Thank for your letter of May 12th . How glad I was when I get it. I'd
be very happy to be your pen friends. Now allow me introduce myself to
you. I'm a boy student aged seventeen, study in Senior Three of Hongqi
High School. I'm a monitor of my class. I am about to take the National
Matriculation Entrance Test after twenty days, that is, between June
7 and 8．You know, I want very much to be a doctor working for poor
peasants that I try to make fully use of every hour and study far into
the night every day.
Best wishes!
Yours truly,
Li Hua
