 Once, when Yuwen Tai was giving his sons horses, Yuwen Xian alone picked a multicolored horse.When Yuwen Tai asked him why he did so, he reasoned that in battle, a multicolored horse would be easier to tell apart from others.Yuwen Tai was pleased with the response, and from that point on, whenever he saw multicolored horses, he would award them to Yuwen Xian.
