Upon the fall of Ming, the Manchus enforced their hairstyle, the notorious queue/pigtail upon the Chinese people, and slayed a good deal of people who Tried to defend their ancestral hairstyle. Some Ming loyalists chose to defy this by shaving all of their hair and adopt a monk's garb, creating a genration of political monks.
What if these loyalists could maintain their influences on Chinese Buddhism after a few genrations, and pull a buddhist uprising against the Qing Dynasty when the time is ripe?
Presumably, if a second Ming Dynasty is created it would be supportive of Buddhism, which would reverse the long-term decline of Buddhism in China since the fall of Yuan, with deep implications on economics and philosophies in China and East Asia.
