What font should I use for birthday invitations?

The birthday invitation is as follows:

1, Mr./Ms. XX: Today is my mother's 80th birthday. Fortunately, I am in good health, and my children and grandchildren are around my knees, so I arranged a thin banquet at the Grand Hotel 1 1: 30 on X year to celebrate my mother's birthday. I sincerely invite you and your family to attend. I also take this opportunity to express my deep gratitude to the nobles, friends and relatives who have cared for and supported us! Waiting for you!

2. Dear XX, hello! I will celebrate my mother's 80th birthday on XX, and invite you to attend. Thank you.

It is my mother's 80th birthday, and I want to invite XX to my mother's birthday party. I'll wait for you at six o'clock and be seated at seven o'clock.

We will hold mother's 80th birthday celebration in a certain place on a certain day, a certain month and a certain time, and invite you to come!

Dear XXX, I will hold my mother's 80th birthday party in a hotel (with specific address) at some time. Sincerely invite you to attend and look forward to your arrival.
