Mencius - Book 3, Part 1, Chapter 4A

There came from Ch'û to T'ang one Hsü Hsing, who gave out that he acted according to the words of Shan-nang. Coming right to his gate, he addressed the duke Wan, saying, 'A man of a distant region, I have heard that you, Prince, are practicing a benevolent government, and I wish to receive a site for a house, and to become one of your people.' The duke Wan gave him a dwelling-place. His disciples, amounting to several tens, all wore clothes of haircloth, and made sandals of hemp and wove mats for a living.

At the same time, Ch'an Hsiang, a disciple of Ch'an Liang, and his younger brother, Hsin, with their plough-handles and shares on their backs, came from Sung to T'ang, saying, 'We have heard that you, Prince, are putting into practice the government of the ancient sages, showing that you are likewise a sage. We wish to become the subjects of a sage.'

When Ch'an Hsiang saw Hsü Hsing, he was greatly pleased with him, and, abandoning entirely whatever he had learned, became his disciple. Having an interview with Mencius, he related to him with approbation the words of Hsü Hsing to the following effect: 'The prince of T'ang is indeed a worthy prince. He has not yet heard, however, the real doctrines of antiquity. Now, wise and able princes should cultivate the ground equally and along with their people, and eat the fruit of their labor. They should prepare their own meals, morning and evening, while at the same time they carry on their government. But now, the prince of T'ang has his granaries, treasuries, and arsenals, which is an oppressing of the people to nourish himself. How can he be deemed a real worthy prince?'
