"Have you never heard how the youth of Shouling went to study at Han-tan? They did not learn what they wanted at Han-tan, and forgot all they knew before into the bargain, so that they returned home in disgrace. And you, if you do not go away, you will forget all you know, and waste your time into the bargain." Kung Sun Lung's jaw dropped; his tongue clave to his palate; and he slunk away. Another spurious episode, as is evident from its general weakness, not to mention repetitions of figures and allusions taken from other chapters. Chuang Tzŭ was fishing in the P'u when the prince of Ch'u sent two high officials to ask him to take charge of the administration of the Ch'u State. Chuang Tzŭ went on fishing, and without turning his head said, "I have heard that in Ch'u there is a sacred tortoise which has been dead now some three thousand years. And that the prince keeps this tortoise carefully enclosed in a chest on the altar of his ancestral temple. Now would this tortoise rather be dead and have its remains venerated, or be alive and wagging its tail in the mud?" "It would rather be alive," replied the two officials, "and wagging its tail in the mud." "Begone!" cried Chuang Tzŭ. "I too will wag my tail in the mud."
