On June 21, 2015, China is hosting the first International taiji and yoga festival in the historic Dujiangyan, to celebrate international Yoga day. Located in the hills outside Chengdu, the natural beauty and serenity has attracted Buddhists and Taoists who built grand monasteries and simple hermitage for centuries. 2,000 years ago, Li Bin and his son created the ancient irrigation system, managing the flood flowing down from the mountains into Chengdu Plain. The result has not only controlled the flood damage, but turned Chengdu Plain into a Heavenly Paradise with constant water supply and abundance of food when the rest of the country was threatened by famine and wars. Dujiangyan Irrigation System is a UNESCO’s World Heritage Site.
