Does Xinghua require every child to give a red envelope when betrothed?

Xinghua betrothed each child to give a red envelope. In Xinghua local custom, when engaged, the man's family should prepare red envelopes for the woman or her elders and children. When relatives have children, each child should give them red envelopes or give them to their peers who are still at school or younger than themselves. This kind of red envelope is mainly a gift, so it needs to be wrapped in advance, and several more packages are needed to facilitate distribution.
