《明史·志·卷二十七》
冬季的最后一月的中旬，卜择日期拿出四祖和太祖、成祖七宗的神位牌，在太祖殿祭祀，是大合祭。
季冬中旬，卜日出四祖及太祖、成祖七宗主，飨太祖殿，为大祫。
In mid-December, the last month of winter, a day was chosen by divination for the major joint sacrifice, when the spirit tablets of four ancestors (the Founding Emperor, the Upholding Emperor, the Illustrious Emperor, and the Benevolent Emperor) and the seven emperors from the Founding Emperor to the Establishing Emperor were taken out and placed in the Founding Emperor’s Pavilion for the sacrifice.
