假如你是王毅，请根据下表中所提供的信息，给Allen写一封电子邮件，介绍一下杨利伟，词数90左右。
Dear Allen,
I'm very excited to tell you that the Shenzhou-V manned spaceship was sent up into space at 9:00 a.m. on Oct.15th, 2003 and landed safely back on the earth at 6:23 a.m. on Oct. 16th.
This made Yang Liwei the first Chinese in space. China has become the third country in the world to send a manned spaceship into space independently.
All Chinese people are proud of this and excited. We should study hard and do more exercise to win more honors for our country when we grow up.
Yours,
Wang Yi
