[Looks like it!
Ive read elsewhere that the proximate cause of at least some of these were Grand Solar Minimums affecting food production/distribution.]
Weather affected everyone in the world. Only China had successful peasant revolts. Elsewhere, regimes either stayed in power or had elites replaced (i.e. wiped out) by other elites. Prior to the modern era, Spartacus was the most successful European non-elite rebel I can think of and he failed miserably. In England, Wat Tyler’s revolt was basically an oversized riot. Whereas these Chinese rebels had financiers, cavalry and all the paraphernalia of the regime’s army, except they were led by peasants. This suggests that China is a vast storehouse of cognitive talent, such that even the dregs are pretty sharp cookies.
