I’ve been reading some stuff by Mao and Sun Yat-Sen, as well as a bunch of wikipedia articles to see the liberal slant.

Specifically:

Analysis of the Classes in Chinese Society by MZ

A Critique of Soviet Economics by MZ

Literature and Art by MZ

The Chinese Revolution and the Chinese Communist Party by MZ

Problems of Strategy in Guerrilla War Against Japan by MZ

The International Development of China by Yat-sen Sun
