3. Duke Yi of the state of Rong was known for monopolizing wealth and profits for himself and for being oblivious to its adverse effects on the society. One should know that wealth and profits are the very sources of survival for hundreds of materials nurtured between heaven and earth. To monopolize them will give rise to an unbalanced situation thereby causing much harm. How can one monopolize the resources when they are needed by so many? To do so will arouse anger from the public. If we teach our lord to monopolize resources instead of urging him to take precaution against major disasters, can his reign last long?

3. 夫榮公好專利而不知大難。夫利，百物之所生也，天地之所載也，而有專之，其害多矣。天地百物皆将取焉，何可专也？所怒甚多，而不备大难，以是教王，王其能久乎？（卷十一 史記上）
