Dear ZhangYu
It's really nice of you to come to see me next week,but i'm so sorry that something urgent happened and i have to go to deal with it.My good friend WangBin will go to meet you at the railway station at 5:00PM.
she is 22,a pretty girl in medium size with long curly hair.And she has a round face with big eyes where a pair of glasses are settled,she is fond of sport and usually wears sports suit,i hope you could recognize her easily.
Yours LiJun
