The Duanwu Festival， which is also called the Dragon Boat Festival， is an ancient Chinese traditional festival， celebrated on the fifth day of the fifth lunar month. For thousands of years， various celebrating activities are held all around the country. Eating zongzi and racing dragon boats are the most pertinent ones， which are said to be in memory of Qu Yuan， a great poet. In some places， people spread realgar wine on the children in the hope of protecting them from the evil spirits. Many people consider May as an especially dangerous time for diseases in a year， and therefore they hang moxa and calamus and things like that around the doors to ward off evil and diseases and pray for good luck.
