Chapter 26, Part 4 - Chuang Tzu

The Confucians rob graves in accordance with the Odes and ritual. The big Confucian announces to his underlings: "The east grows light! How is the matter proceeding?"

The little Confucians say: "We haven't got the graveclothes off him yet but there's a pearl in his mouth! Just as the Ode says:

Green, green the grain
Growing on grave mound slopes;
If in life you gave no alms
In death how do you deserve a pearl?"

They push back his sidelocks, press down his beard, and then one of them pries into his chin with a little metal gimlet and gently pulls apart the jaws so as not to injure the pearl in his mouth.
