Dear Snoopy,
I am greatly honored to formally invite you to participate in Mr. Guo Jing’s wedding ceremony with Ms. Huang Rong to be held at Beijing Grand Hotel from 8 to 10 p.m. on April 1, xxxx.
As you are a close friend of us, we would very much like you to attend the celebration and share our joy. The occasion will start at seven o’clock in the evening, with the showing of their wedding ceremony.
This will be followed by a dinner party. At around ten, we will hold a small musical soiree, at which a band will perform some works by Bach and Strauss.
If you do not have any prior appointment on April 1, we look forward to the pleasure of your company.

Dear XXXX,
XX and I have set the date — and we want you to be the first to know it. We’re going to be married very quietly at the Community Church on Thursday, June the twelfth, at noon.

We’ll be looking for you, XXXX, at eleven!
With my best regards!
With Love,
