Dear Mike Teacher,
Hope this email finds you well.
The purpose of this letter is to invite you to a discussion. We hope that you can discuss the need for earthquake escape exercises in the classroom with students.
As you know, on May 12, 2008, a major earthquake occurred in Wenchuan, Sichuan, China. It severely damaged more than 100,000 square kilometers, causing 69,227 deaths, 374,643 injuries and 17,923 missing. This earthquake is the most destructive earthquake in China since its establishment.
These great losses also remind us to always be alert to the harm from natural inadvertent. Our ability to respond to emergency situations needs to be improved. So there was an invitation for this event.
I hope to hear from you.
Yours Sincerely,
Li Hua
