In order to restore the rivers and mountains of the Jin Dynasty, zu Ti led several northern expeditions and recovered a large area of land south of the Yellow River.
One year, he led an army to engage Shi Jilong, nephew of Shi Le, the leader of the Qiang clan in the north. On the way to defeat, Shi Jilong captured Yuzhou, leaving the general Peach Leopard to guard an isolated city.
Zu Di took advantage of the victory and sent the vanguard Han Qian to attack the Peach Leopard. Han and Tao played chess against each other, and after repeated fierce competitions, no one could take advantage, and the result was a stalemate in the isolated city: Han Qian occupied the East City, and the Peach Leopard was stationed in the West City. The two sides fought and stopped in a tug-of-war manner, and the stalemate lasted for more than forty days, and the military food was almost exhausted. When Zu Ti heard Han Qian's report on asking for aid in grain and grass, his heart was very anxious: The military salaries at the headquarters were also in short supply, so where to prepare grain?
Zu Di had been plotting for a long time, and he had calculated it. One day, he ordered the officers and men to take out thousands of empty rice bags, pour loess into the rice bags, and place them on the ground one by one. Then, a grain transport team of a thousand people was organized, and another elite soldier was sent to escort the "military food" to the Dongcheng where Han Qian was stationed. In addition, he sent several soldiers carrying several bags of genuine grain, followed the transport brigade, pretended to be tired and left behind, and stopped at the side of the road to rest. When the peach leopard saw the situation, it immediately sent troops to avoid the truth and let go of Zu Ti's grain transport brigade to rob the grain that was "left behind.". When the "left behind" grain carriers saw the enemy army flocking to them, they deliberately abandoned the grain and fled according to Zu Ti's orders. The Tao Army happily snatched the bags of grain.
The grain was handed to the peach leopard, and when I opened my pocket, I saw that it was all rice with white flowers. Because the officers and men of the Tao Army had not eaten enough for many days in a row, they stared like hungry wolves one by one. Peach Leopard waved his hand, signaling that he could cook rice, and his subordinates rushed up, but only some of the soldiers grabbed it, most of the soldiers did not catch a grain of rice, and they scolded the mother, thinking that the Korean army in Dongcheng had obtained a large amount of grain for help, and no longer had the heart to fight. The peach leopard was anxious and hateful, and had to send people to urge Shi Le to transport grain to rescue him.
Upon hearing the news, Shi Le immediately raised a large amount of military food and organized the transportation of grain donkeys and horses to send to the peach leopard. Zu Di had already anticipated that the other side would make such a move, and ordered Han Qian and others to send heavy troops to intercept them in the area of Beishui, through which the enemy must pass, and capture all the grain.
