Dear Xu Yan,How is everything going these days? I am writing to invite you to an outing on Sunday, May 10th. We will meet at the school gate at 6:30 in the morning and then go to Yongfeng Mountain by bus. We will climb the mountain there in the morning and then have a picnic at noon. If you can come, you don’t need to bring food but it’s best for you to wear sports shoes and suitable clothes.
