Thank you for your letter, what really made me happy. I’m glad to know that you’ve come China to learn
kung fu in a school in my hometown. I’m surely you’ll have a good time. Actually, I start to learn kung fu when I
was seven years old, for I have long been out of practice. Luckily, I will go home in two weeks for summer
vacations. Then I can spare some time to learn it again, such that we can practice together on every day. Best of
luck with yours learning kung fu in China. See you sooner.
