How to write the birthday invitation?

An invitation to Wen Yi, a birthday party fan.

Dear Ms./Mr. XX

I'm going to hold a birthday party on June 14 this month. I hope that friends who are free will attend on time and refuse to bring their own drinks and all gifts. I will bear all the drinks, cakes and free lunches. Only with a sincere heart, bless me, thank you!

Time: April 20XX 14.

Venue: Hu Xiaonan Garden Square

Look forward to your visit!
