1. Eat the five reds on the Dragon Boat Festival, which are "roast duck, amaranth, duck eggs with red oil, lobster, and realgar wine." It is said that eating these five reds on the Dragon Boat Festival can ward off evil spirits and avoid the heat throughout the summer.

2. Legend has it that a long time ago, the Jade Emperor announced that poisons in the sky would not be able to enter the mortal world until the first sound of spring thunder, so people called that time the Waking of Insects. However, some poisons are afraid of the cold, so they make an appointment to harm the world together when the weather gets warm during the Dragon Boat Festival. These five poisons are snakes, spiders, scorpions, centipedes and geckos.

3. They came to the world during the Dragon Boat Festival. As soon as they arrived at the door of a house, they heard the hostess of the house saying: "Eat quickly, these are the five poisons of deep-fried food." The five poisonous people were shocked, so they leaned down to the window and looked. They saw five red dishes on the five plates on the table. The hostess said while eating: "These five poisonous vegetables are so delicious." The "five red vegetables" turned into their blood in the eyes of the five poisonous creatures. The five poisonous creatures were so frightened that they fled from the house in a hurry and never dared to go there again.

4. From now on, people will eat five kinds of red vegetables on the Dragon Boat Festival to scare away the poisonous animals, hoping that they will not enter their homes. Therefore, the so-called "Five Reds" have become a must-have menu on the Dragon Boat Festival table.
