Are there any parents who don't know their children on their birthdays?

Not surprisingly, unlike now, the birth certificate clearly States the detailed time.

In addition, if your parents don't tell you the time, they may not want you to indulge in life without working hard! Actually, it's good for you, too

After all, some people don't work hard when they know that life is good, or give up when they know that life is bad. They should know whether their life is good or not, or they should work hard on their own.

Come on!
