Dear Judy,
I am very glad to write to tell you about myself.
I am Yang Fan, and I am twelve years old. At my age, like most Chinese students, I am very busy. I have to go to shcoo at half past seven in the morning and go home at five o'clock in the afternoon. Regarding to my hobbies, music and English are my favouriate subjects becuase I find them are interesting. Yours,
Yang Fan
