My father's 70th birthday, how to write a group short message?

My father's 70th birthday, I can send you a group message for treatment, or I can express it according to my own ideas, such as: Dear friends, we sincerely invite you to meet at a certain place on a certain day. This day is my father's 70th birthday. Let's have a drink and enjoy it.

For example, please give your work a holiday, please move your entertainment, please prepare your red envelope, please bring your blessing to my father's 70th birthday. With your blessing and your presence, the birthday party will be radiant, especially your red envelope, which will make me happy, haha! Don't refuse, don't come, please come!
