Attachment: First, the magic weapon of water control left by Li Bing and his son-deep Taotan low weir
"Deep scouring beach, low weir, pumping heart everywhere, cutting corners everywhere." It is the motto of water control left by Li Bing and his son who built Dujiangyan. It was Li Bing and his son who mastered the law of water control and successfully built Dujiangyan. Today, with the development of modern science and technology, people are still amazed at Li Bing and his son.
Dujiangyan is divided into three parts: fish mouth, treasure bottle mouth and flying sand weir, which undertake the functions of diversion, flood discharge and sand discharge respectively, which is scientific and reasonable. According to historical records, Dujiangyan came first, and then the land of abundance in Chengdu Plain. More than 2600 years later, Dujiangyan continues to play a great role in flood control and irrigation.
"Deep scouring the beach" is to dig deep into the river bed and let the water flow in its own river. "Low weir" means to stop water without relying on dikes and give full play to the role of nature.
In the process of managing society and people, we must pay attention to this problem. Relying on correct policies, we should guide people to give full play to their subjective initiative, instead of excessively restricting people's behavior and interfering in people's lives.
"Pumping the heart when the river is in time" means cleaning up the center of the river to make the water flow smoother, similar to "low weir". "Cutting the corner in case of bend" means cutting an angle at the bend of the river, which can reduce the impact on the right bank levee, make the water flow smooth and ensure the safety of the river.
Secondly, there is a couplet in the "Erwang Temple" next to Dujiangyan: "Every bend must be cut", which means that if there is a bend in the river, the right angle must be turned into a radian, which is called "Daojiao" in the current professional terminology. This will make the river flow more smoothly without damaging the dam. This is the meaning of cutting corners. "Everything is pumped out of the heart" means that in the center of the main river, it must be dug deep to let the river flow along a certain track, just like the current urban light rail must run on the track.
