Part of their faith in Communism stems from the Sinocentric belief that whatever the Self-Anointed "Central Nation" is practicing MUST, by nature, be better than anything else in the world. If Xi repudiated Communism tomorrow and declared China a Capitalist country, they would all swear Capitalism was the greatest system known to man and that China was the best in the world at it.
Chinese students are taught from an early age that the Chinese State is infallible.
I'm not speaking on hearsay either.
I teach in their public schools.
