Follow the seasons of Xia. Ride in the state carriage of Yin. Wear the ceremonial cap of Zhou. Let the music be the Shao with its pantomimes. Banish the songs of Zheng, and keep far from specious talkers. The songs of Zheng are licentious; specious talkers are dangerous.
行夏之时，乘殷之辂，服周之冕，乐则韶舞。放郑声，远佞人。郑声淫，佞人殆。
