Li Bing (Qin)

[2] King Zhaoxiang of Qin (r. 306–251 BC) dispatched Li Bing as a joint military and civilian governor (shou) over Shu, a recently defeated state in Sichuan province, Southwest China, just west of modern Chengdu.

[5][6] He arrived just as Zhang Ruo had put down the last of the marquis rebellions and moved out to engage the Chu city of Yan.

"When he arrived in Shu, Li Bing witnessed the sufferings of local people from frequent flooding of the Min River."

[7] Li Bing then created “the largest, most carefully planned public works project yet seen anywhere on the eastern half of the Eurasian continent.”[attribution needed] It would be called Dujiangyan.

[8] On the other hand, the water diversion would have a positive effect and on the Qin system of land distribution with wet paddy rice in the Chengdu plains.

When the river deity did not drink his glass of wine, Li, deeply offended, ran off with a drawn sword.
