Dear Mr Smith,

I am Li Hua, Chairman of the Students’ Union. I am glad to invite you on behalf of the Students’ Union to attend an outing which is to be held at Nan Shan next Sunday.

If you are willing to go with us, please make sure of the following things. We will gather at the school gate at 7:30 in the morning on Sunday. It couldn’t be better if you can come to meet us on time. Then we will go there by bike together. Things that should be taken with us will include necessary food, water, clothing, a camera and so on.

Please make sure to let us know before next Friday whether you will join us. We are looking forward to your reply.

Yours sincerely,

Li Hua
