Does it take 99 days for children to see their centenarians?

0/00th day for girls/kloc, and 99 days for boys (one day in advance).

When the baby is born 100 days, it should be celebrated and called "100 years old or older". Family, aunts and grandmothers should get together to celebrate. In the wedding gift, there should be trousers sewn with velvet spikes, the sound of "spikes" is in harmony with "years old", and other clothes, fabrics, bracelets and silver locks. Silver lock means to lock a person's life and wish him a long life, also known as longevity lock. In addition, children are given "centenary clothes" and "centenary sunshine" for "centenary". Most rural areas in the north regard flour as "centenarians", that is, pasta with a thick garden in the middle and pointed gardens at both ends, which can be large or small and edible, and given to relatives and friends on the same day.
