Legend has it that the white tiger that has been hibernating for a whole winter will start to come out and move. The white tiger is also in charge of the tongue and right and wrong. White tigers usually open their teeth and feed them eggs. When they are full, they won't hurt people. If you are full, you will not attack the villagers again, so as to pray for peace, health, good luck and happiness. Therefore, there is also the custom of offering sacrifices to white tigers and eating eggs on this day. Today, although there is no scientific basis, people just hope to be lucky, which means that the new year can go smoothly, not be destroyed by bad things, stay away from all kinds of right and wrong, and make waves.
