The boat races during the Dragon Boat Festival are traditional customs to attempts to rescue the patriotic poet Chu Yuan. Chu Yuan drowned on the fifth day of the fifth lunar month in 277 B.C. Chinese citizens now throw bamboo leaves filled with cooked rice into the water. Therefore the fish could eat the rice rather than the hero poet. This later on turned into the custom of eating tzungtzu and rice dumplings.
The celebration's is a time for protection from evil and disease for the rest of the year. It is done so by different practices such as hanging healthy herbs on the front door, drinking nutritious concoctions, and displaying portraits of evil's nemesis, Chung Kuei. If one manages to stand an egg on it's end at exactly 12:00 noon, the following year will be a lucky one.
