Dear Wang Fei,
I'm writing invite you to go back to our senior high school to join her sixty anniversary celebration. It has been three years since we graduate from high school. The celebration would last in three days from October 1st to October 3rd. Schoolmates will gather to meet their friend. The evening party will be held, that folk songs will be performed. Students' group dance will be shown as well too. We'll raise money to set up a scholarship to provide financial support for the students from rural areas. I'm looking forward to your come.
Yours,
Li Hua
