The tombs dating to the early Spring and Autumn period in the Zhaojiahu cemetery in Dangyang,notably no.ZHM2 and ZHM3,are the vital archaeological examples for studying the origin and development of ritual vessels used in Chu style tombs.A striking consistency is observed in the use of pottery gui vessels and presence of an even number and identical vessels between Zhao Jiabang's tombs no.ZHM2 and ZHM3 and Yin remnants during the Western Zhou period.Moreover,the practice of using even numbers of identical ding vessels,prevalent in the Chu region,likely has roots in the Yin tradition.Similar ritual customs are also evident in the Huaiyi cultural relics adjacent to the Chu region.By examining the hierarchical differences between the'even numbers of identical vessels'and the use of an even number of tripods in a set,as well as the'Zhou ritual'style reflected in the scale of the tomb and the types of burial objects in the Zhao Jiabang Cemetery,this study reveals two major origins of the Chu-style tomb ritual customs:the'Yin system'(old customs)and'Zhou ritual'(Zhou system).
