On one occasion when Tian Yu went to besiege Kebineng's father-in-law for instance, Kebineng came to assist with tens of thousands of cavalry and would have defeated Tian Yu had he not been persuaded by his advisers and a diplomat, Yan Zhi, to call for a cease-fire. The power of Kebineng's tribes did not significantly wane in any case until his death, but before Kebineng did die, he managed to initiate several devastating raids on You and Bing provinces. When Kebineng finally did meet his end, there was a period of relative peace between the Xianbei and Han Chinese for several decades.
