Question

 Li Bing was born during the Warring States Period. He was an official from the State of Qin. Around 277 B. C.，Li Bing received an order which controlled the flood in Chengdu.

  With that special task in mind，Li Bing did very wide field study in and around Chengdu. Around 256 B. C.，he and his son decided to put their idea to the test. They built Dujiangyan about 56 kilometers ( or 35 miles) west of Chengdu. Their design had three important parts.

  The first part is called Yuzui. Yuzui means "fish mouth" in Chinese. It was a man-made island. It controls how much water each stream gets. The second part is called Feishayan. It is really a spillway(泄洪道)that forces the sand and little stones from the inner river to the outer river. The third part is called Baopingkou. It controls how much water from the inner(内部的)river is to be used for irrigation(灌慨).

  Li Bing and his son spent nearly five years on building Dujiangyan. They finished it around 251 B. C.

By today's standard, Dujiangyan may be not so prefect. But to truly appreciate(欣赏) Dujiangyan,we must remember that it was built more than 2,200 years ago. Back then,the Chinese did not have any modern machines. But they still made many great things they had on hand. Just like that,they built Dujiangyan. It is amazing, isn't it?
