《逸周书·卷六·月令解》
这个月，天子诸侯与群臣在蒸祭之后，举行盛大的宴饮，排列次序。天子向包月星辰等在天之神祈求明年五谷丰登。大杀牺牲，在官社及门闾祈祷，然后飨先祖，五祀，慰劳农夫，使他们好好休息。
是月也，大饮蒸，天子乃祈来年于天宗，大割祠于公社，及门闾，飨先祖五祀，劳农夫以休息之。
This month, after the Z蒸祭, the emperor, feudal lords, and ministers held a grand banquet in order of rank. The emperor prayed to celestial deities such as the Moon and stars for a bountiful harvest the following year. Major sacrifices were made and prayers were offered at government shrines and gateways. Ancestral spirits and the Five Deities were then feasted, and farmers were rewarded to allow them to rest.
