He Xiu 何休 demonstrates that, with the exception of the state of Lu 魯, large, small and tiny states followed different principles for recording the deaths (卒 zu) and burials (葬 zang) of feudal lords. In large states, it was necessary to record both the date when a king died and the month in which he was buried, and this principle did not vary. In the small and tiny states, the manner of recording death and burial dates differed over time. Though a tiny state of the Zhou dynasty, Qi 杞 had its own rules for recording deaths and burials. The non-Han states Chu 楚 and Wu 吳 followed different ways from the Central Plains states. Qin 秦, though a Han state, in many ways behaved like a non-Han state, and differed from both the Central Plains states and Chu and Wu in the recording of deaths and burials. With the exception of Lu, He Xiu demonstrates the ways in which the date of death and the month of burial of the feudal lords were recorded. He records the date together with the month and makes some breakthroughs in understanding the principles.
