““During China’s War of the Three Kingdoms (A.D. 207-265), the great general Chuko Liang, leading the forces of the Shu Kingdom, dispatched his vast army to a distant camp while he rested in a small town with a handful of soldiers. Suddenly sentinels hurried in with the alarming news that an enemy force of over 150,000 troops under Sima Yi was approaching. With only a hundred men to defend him, Chuko Liang’s situation was hopeless. The enemy would finally capture this renowned leader. Without lamenting his fate, or wasting time trying to figure out how he had been caught, Liang ordered his troops to take down their flags, throw open the city gates, and hide. He himself then took a seat on the most visible part of the city’s wall, wearing a Taoist robe. He lit some incense, strummed his lute, and began to chant. Minutes later he could see the vast enemy army approaching, an endless phalanx of soldiers. Pretending not to notice them, he continued to sing and play the lute. Soon the army stood at the town gates. At its head was Sima Yi, who instantly recognized the man on the wall. Even so, as his soldiers itched to enter the unguarded town through its open gates, Sima Yi hesitated, held them back, and studied Liang on the wall. Then, he ordered an immediate and speedy retreat.””
