Every animal year, adults and children should wear red belts and red hand ropes, commonly known as "tying red", and children should also pass on red vests and red underpants, thinking that only in this way can they avoid disasters, thus pinning people's wishes for longevity, health and good luck. The red rope in the animal year is considered lucky and disaster-free, because China people like red, which means good luck. Red is the color of the sun, blood and fire.
