Chang said, 'In that case, then, did not Shun rejoice hypocritically?' Mencius replied, 'No. Formerly, some one sent a present of a live fish to Tsze-ch'an of Chang. Tsze-ch'an ordered his pond-keeper to keep it in the pond, but that officer cooked it, and reported the execution of his commission, saying, "When I first let it go, it embarrassed. In a little while, it seemed to be somewhat at ease, then it swam away joyfully."Go here to read the introductory post to this serialized version of the Works of Mencius.
'Tsze-ch'an observed, "It had got into its element! It had got into its element!" The pond-keeper then went out and said, "Who calls Tsze-ch'an a wise man? After I had cooked and eaten the fish, he says, "It had got into its element! It had got into its element!" Thus a superior man may be imposed on by what seems to be as it ought to be, but he cannot be entrapped by what is contrary to right principle. Hsiang came in the way in which the love of his elder brother would have made him come; therefore Shun sincerely believed him, and rejoiced. What hypocrisy was there?'
