Can't you have a birthday?

1. From birth to 16 years old, this child is a "god" rather than a person. We can all celebrate our children's birthdays, even if it is a big event.

2. 17 to 59 years old, people have changed from "gods" to people, and they can celebrate their birthdays, but they should celebrate their birthdays according to local customs. For example, every tenth birthday is usually one year earlier. For example, the 30th birthday is usually completed at the age of 29. And in many places, "three but four", that is, the thirtieth birthday can be celebrated, and the fortieth birthday can't be celebrated.

3. When a person is 60 years old, it is already the cycle of 60 children. Therefore, from the age of 60 to 80, it is impossible to celebrate birthdays in a big way. In the past, both anecdotal and personal psychology believed that once people reached the age of 60, they could not celebrate their birthdays, because they were afraid of "reminding" the horrible prince and "finding out" those who celebrated their birthdays early.

At the age of 80, people become "gods", so they can celebrate their birthdays, even if they celebrate their birthdays in newspapers, because they are already "gods" and not people.
