Tsze-chang asked whether the affairs of ten ages after could be known.
Confucius said,
“The Yin dynasty followed the regulations of the Hsiâ: wherein it took from or added to them may be known. The Châu dynasty has followed the regulations of Yin: wherein it took from or added to them may be known. Some other may follow the Châu, but though it should be at the distance of a hundred ages, its affairs may be known.”
