There are exact records in history books, and the figures are clear. The biggest example is that in the early Sixteen Countries of the Eastern Jin Dynasty, after the establishment of Xerox in the northern part of the Sixteen Countries, after the death of Shi Hu, the second emperor, all the 30,000 ladies-in-waiting (that is, ladies-in-waiting, mostly beautiful women) who stayed in the palace were eaten up. That was the worst time.
