Zheng Guo

Zheng Guo or Cheng Kuo (鄭國) was a hydraulic engineer from the ancient Chinese kingdom of Han who designed the Zhengguo Canal in the kingdom of Qin during the Warring States Period^[1]. The canal remains to this day, despite having been constructed in the third century BC. The canal was originally designed as a method to trick the ruler of Qin so that Qin could not expand to the east. However, when it was completed, it was a great agricultural boost to the region^[2].
