This sentence is a famous saying of the world-famous Dujiangyan water conservancy project. These six-character water control classics not only reflect the excellent ideas and thoughts of the ancients, but also have important reference significance for modern people's life management and enterprise management.
Dujiangyan is the most famous water conservancy project in ancient China, located in guanxian, the middle reaches of Minjiang River in Sichuan. It turns out that the water in the upper reaches of Minjiang River is fast-flowing. After entering guanxian, the terrain suddenly becomes low, the water potential slows down, and it carries a lot of sand and gravel deposits, which silts up the river and often overflows. Under the auspices of Li Bing and his son, the guards of Qin and Shu counties, the method of "irrigating fields with water to divert floods and reduce disasters" was adopted. From 256 BC to 25 BC1year, isolation piles connected with Hutou Mountain were successively dug in the Minjiang River west of guanxian, and diversion dikes and dams were built upstream of the isolation piles to divide the Minjiang River into two tributaries, Neijiang River and Waijiang River, and sluices were built to regulate the flow of the two rivers, thus dispersing the flow of the Minjiang River. Dujiangyan Water Conservancy Project has ensured the irrigation of about 3 million mu of fertile land, making Chengdu Plain a "land of abundance" for drought and flood. Dujiangyan Water Conservancy Project still irrigates Chengdu Plain, which is a preserved water conservancy project still in service in the world. Can serve today, all because of the most critical six words-deep scouring beach, low weir.
