From the introduction:
The Manchus invaded China in 1644, and by 1681 had succeeded in completely deposing the Ming Dynasty. Even after the Manchus were ensconced in power, rebellious groups continued to spring up, many set on reviving the Ming Dynasty and ousting the foreign Manchus. For the next two centuries, rumors of hidden Ming treasure ran rampant, but the truth of this rumor always seemed in doubt. Until now.
