During the Dragon Boat Festival, you should not only eat zongzi, but also eat duck eggs. In addition to commemorating Qu Yuan, the Dragon Boat Festival is to avoid the five poisons, because the legendary five poisonous monsters will harm the human world during the Dragon Boat Festival. These five poisonous monsters are snakes, centipedes, spiders, geckos and scorpions. People eating these dishes will scare away the five poisonous monsters, that is, eating five reds, namely roast duck, amaranth and scorpion.
Similar to Wu Hong, Jiangnan also has the custom of eating Huang Wu during the Dragon Boat Festival. Huang Wu refers to eel, yellow croaker, cucumber, salted duck eggs and realgar wine. Whether in Wu Hong or Huang Wu, there are duck eggs, so eating duck eggs during the Dragon Boat Festival has the reason to ward off evil spirits and dispel summer heat.
