Bamboo drift racing has now become a designated national sport. During the competition, the competitor stands on a floating bamboo pole in the water, and paddles it with a thin stick of bamboo.

Bamboo drifting was originated about 100 years ago and later became popular pasttime among people of ethnic minorities in Southwest China's Guizhou Province. Guizhou's high mountains and deep valleys maintained a constant state of flooding, and made traveling in and out of the area difficult. Local people overcame the problem by chopping down bamboo logs and drifting along on them down the river. Upon reaching the bazaar on the lower reaches of the Wujiang River, they would sell their bamboo conveyance. The practice survives to this day.

Dragon boat racing was originated in China over 2000 years ago. A dragon boat is a very long and narrow canoe-style human-powered boat, and is generally rigged with decorative Chinese dragon heads and tails. While competition has taken place annually for more than 20 centuries as part of folk ritual, it emerged in modern times as an international "sport" in Hong Kong in 1976.
