The Dragon Boat Festival follows the Beginning of Summer. It is the custom to eat zongzi (rice dumpling wrapped in reed leaves). According to the stuffing, the zongzi includes rice zongzi, meat zongzi, cowpea zongzi and black date zongzi. There are hexagonal zongzi, triangle zongzi and quadrangle zongzi. Accompanying the zongzi, six or nine dishes should be prepared, traditionally including large yellow croakers and braised pork in brown sauce. The adults and children also drink realgar liquor. The liquor is used to draw a Chinese character "王" (king) on the children's foreheads or applied to the children's ears, which is said to have the power of avoiding evil spirits and insects' bites. Swords made of calamus and wormwood hang on every door to ward off evil and bad luck. Clam powder and realgar liquor are cast in the corners of the house to fend off bad luck and poisonous animals like snakes or scorpions. It was the custom to give perfume sachets at the Dragon Boat Festival in the past. Women would embroider the patterns of flowers, birds, animals, insects, fishes and figures on the sachets in the shapes of fruits, hearts or circles and fill them with fragrant herbs. There were also sachets with only a camphor ball inside. The sachets are taken by the children or hung on the mosquito net to repel insects and clean the air.
