'Contradiction', the last known set of cartoons Huang Yao painted
before leaving China. It depicted the contrasting situations between
the old and the young, modern and traditional; the injustice committed
by the government and military towards the civilians, the rich and
the poor, the politicians, business men, scientist's view of the world,etc.
The painting here is about a poor professor needing to carry water
(for his own consumption?) while his students in fashionable clothes
had time and mood to engage in courtship.
