In China, Chengdu is always praised as the Tian Fu Zhi Guo,
which means 'Nature's Storehouse'. Over 2,200 years ago, the
city was threatened by the frequent floods caused by flooding
of the Minjiang River (a tributary of the Yangtze River ). Li Bing,
a local official of Sichuan Province at that time, together with
his son, decided to construct an irrigation system on the
Minjiang River to prevent flooding. After a lengthy study and a
lot of hard work by the local people, the great Dujiangyan
Irrigation Project was completed. Since then, the Chengdu Plain
has been free of flooding and the people have been living
peacefully and affluently. Now, the project is honored as the
'Treasure of Sichuan', which still plays a crucial role in draining
off floodwater, irrigating farms and providing water resources
for more than 50 cities in the province.
Dujiangyan is the oldest and only surviving no-dam irrigation
system in the world; and a wonder in the development of Chinese
science. The project consists of three important parts, namely
Yuzui, Feishayan and Baopingkou scientifically designed to
automatically control the water flow of the rivers from the
mountains to the plains throughout the year.
