Shopping malls and shops sell wedding invitations, not to mention their covers. You know what's in it, right? Send it to a platform, hold a wedding for someone at a certain time and place on a certain day, and sit down several times. There are many samples on the Internet. You can just Baidu them. There is no need to write them yourself. Just buy an invitation and fill it out yourself. It's beautiful. If you eat at home for a day, write down who will get married in this humble abode on a certain day of the year, and write down that you will wait for someone to have breakfast at nine or ten o'clock. Even if you don't write down the local customs, people will know when to come.
