Usually, when the new year comes, the elders will give the younger generation red envelopes and lucky money, and on New Year's Eve, they will put it under the pillow, and the younger generation will say something to wish the New Year. In ancient times, people thought that red envelopes on New Year's Eve could suppress evil spirits, so lucky money had the hope of passing the coming year safely and smoothly. In addition, in weddings, birthdays and other occasions, there is also the habit of issuing red envelopes, which is a good wish.
