The king of the state of Chu heard about this and thought it was extraordinary. He sent for Zhan He to ask how he did it.
"Sire," said Zhan He. "I heard my late father say that when the skilled archer Pu Qiezi shot at birds, he had a rather flmimsy bow and used a slender string to attach to his retrievable arrow which was shot along the direction of the wind. He hit two orioles in the cloud with one arrow because of his total concentration and the exquisite evenness of his touch. Sire, I used him as an example and learned to fish. It took me five years to perfect my technique. When I come to the river bank with a rod in my hand, I have no other thought in my mind except fishing. When I cast the line and let the hook sink into the water, my touch is neither too heavy nor too light and nothing can distract me. To the fishes, my hook and bait seem like bits of mud and froth in the water, so they swallow them without suspecting anything. This is how strength can be overcome by weakness and what is heavy can be got my what is light.
