During this time, Guan Yu had a standoff with Lu Su at Yiyang, where he planned to lead 5,000 elite soldiers to cross the upstream shallows at night. In response, Lu Su ordered Gan Ning to lead 1,000 troops to guard their side of the shallows. Guan Yu did not dare to cross the shallows and instead ordered his men to make camp on their side. The shallows were thus named 'Guan Yu's Shallows' (關羽瀨).
