                1. The most general and comprehensive term for a villain is zéi 賊, and the basic association is with the damage he does. There is no special association with murder or thievery.

                3. Dào 盜 refers to thieves or the more ordinary kind, and burglars, and the basic association is with the property he romoves. Note that Dào Zhí 盜跖 is something of a euphemism, since this gentleman was an arch-villain of great dimension.

              • SLAVE

                Slavery and servant-hood not always easy to distinguish, and this is for very interesting social reasons. A scheme for the place of menials in the status system is systematised in a crucial ZUO Zhao 7 passage:

                故王臣公,公臣大夫,大夫臣士,士臣皁,皁臣輿,輿臣隸,隸臣僚,僚臣僕,僕臣臺。
