What is the commemorative significance of taking a hundred days for the baby?

In the folk, a hundred-day baby doesn't talk about a hundred days, but talks about "a hundred years old", which means that the baby grows up healthily and has a lucky and smooth life. Most families regard the baby's centenary birthday as more important than the full moon banquet. Some hold centenary banquets, and some elders prepare longevity gold and silver locks for their babies, which means to lock the health and happiness of their babies from the age of 100. It is the first time for a child to sit up and get in close contact with his parents in front of the camera. It is also a good wish of parents to pray for a long life without disease and disaster.
