Dear Wang Jing, As you know, ping-pong is popular with foreign students in our school, but it's difficult for us to play it well. However, playing ping-pong is a piece of cake for you, so we want to invite you to teach us how to play it. The activity will be on the afternoon of December 3rd. Please reply to this invitation by November 25th. Hope you can make it! Vince Jones, Student Assistant of Foreign Students' Service Center
