According to the old rules in Nanjing, at noon on the Dragon Boat Festival, every household should put the whole garlic in a pot and cook it for the children. A child eats one alone, because homophones are poisonous. The child ate burnt garlic, so he didn't have diarrhea in summer and there were no bugs in his abdomen. Every family must eat amaranth. It is said that abdominal pain can be avoided in summer.
