When the baby is full moon, it is inevitable to pray to the gods and ancestors, and then shave the fetal hair. Adults always hope that the baby will grow up quickly. On the day of the full moon, grandparents will give their little baby many full moon cakes, hoping that their grandson (daughter) can win the first prize and live a happy life.
With the progress of the times, giving a cake at the full moon means "puffing hair", wishing the baby a prosperous future.
