“During the reign of emperor Ning Zong of the Southern Song Dynasty, the Jin tribal army attacked China. A capable general, Bi Daibi, beat off the Jin attack. But the determined Jin sent tens of thousands of cavalry soldiers to besiege the Song camp.The Song forces were very worried. They had only a few thousand soldiers. But Bi Daibi thought of a brilliant plan.Seeing that the Song forces did not react, the Jin troops were wary, but returned to their camp first. That night, the sounds of war drums rang out and the Song flags were raised. The Jin troops scrambled, ready to fight the enemy.The beating of the drums went on but no troops emerged to fight. It went on for three days. The Jin thought that the Song forces were trying to keep them alert. Having no rest, the Jin troops returned to their camps.Only when the sound of the war drums became faint did the Jin troops dare to enter the Song camp. The Jin found many goats with their hind legs tied to a tree and a drum placed underneath the fore legs. The beating of the drums came from the trembling fore legs of the goats. The Song forces have retreated three dys ago. “
