Yang was a general of Chu in the Spring and Autumn Period. He once shot General Jin and Dou Yuejiao. There are many allusions related to Yang, such as hitting the target with a hundred shots and penetrating Yang with a hundred paces. Allusions to Yang's story can be found in Historical Records of Zhou Benji, Warring States Policy, Western Zhou Policy and other ancient records.
In order to support the people, after the country was destroyed by Chu, Yang became a doctor of Chu. According to legend, Yang Neng shot through willow leaves a hundred paces away as a mark, and shot through seven layers of armor with one arrow. "The Warring States Policy and the Western Zhou Strategy" records: "Anyone who has Yang Yuchu is good at shooting. Go to the willow tree and shoot it. " It all started here. This man's name is "holding an arrow", and one arrow is enough to win.
