简介：It was rare for civil servants in this dynasty to beat drums to assist in battles. One was Yu Qian, the Minister of War during the capital defense war after the Tumubao Incident, and the other was Yuan Chonghuan, the Liaodong manager during the Jisi Incident. During the battle of Guangqumen in the capital, Yuan Chonghuan wore heavy armor and went on stage to beat drums in person. The prisoners shot heavy arrows. The arrow shaft hanging on his body looked like a hedgehog.
