[单项选择]The Dragon Boat Festival is one of the three major Chinese traditional festivals, along with Spring Festival and the Moon Festival. Of the three, it is possibly the oldest, dating back to the Warring States Period. As the term suggests, dragon-boat is a boat caved like a dragon. The origin of the dragon-boat race is related to Quyuan, a senior official of Chu in the period of the Warring States. He hated the crafty sycophants in the important positions. At last, he was squeezed out by them and exiled. He threw himself into a river on the fifth of the fifth lunar month in 278 BC. The local people organized spontaneously to rescue him by rowing boat. However, the rescue ended in vain. This common practice developed into the dragon-boat sports to memorize Quyuan.
The dragon-boat race has become a custom since Tang Dynasty. To win the race, the following must be concerned about:
1. High quality wood. Heavy wood will affect the speed, so it is usually made of light wood.
