Gun

Gun, Earl of Chong was a ruler of the State of Chong during the Taotang-shi and Youyu-shi eras of the Three Sovereigns and Five Emperors period of traditional Chinese historiography. He is said to have been the father of Yu the Great, the founder of the Xia dynasty. As ruler Chong, Gun was appointed to the task of controlling the Great Flood by Emperor Yao on the advice of the Four Mountains. Gun used dykes to try to stop the flooding, but the dykes collapsed, killing many people, leading to either his execution or exile by Emperor Shun, depending on account. He is thus labelled as one of the Four Criminals.
