What kind of spirit is this that makes a foreigner selflessly adopt the cause of the Chinese people's liberation as his own? It is the spirit of internationalism, the spirit of communism, from which every Chinese Communist must learn…. We must unite with the proletariat of all the capitalist countries, with the proletariat of Japan, Britain, the United States, Germany, Italy and all other capitalist countries, before it is possible to overthrow imperialism, to liberate our nation and people, and to liberate the other nations and peoples of the world. This is our internationalism, the internationalism with which we oppose both narrow nationalism and narrow patriotism.
A communist must be selfless, with the interests of the masses at heart. He must also possess a largeness of mind, as well as a practical, far-sighted mindset.
Communists must be ready at all times to stand up for the truth, because truth is in the interests of the people; Communists must be ready at all times to correct their mistakes, because mistakes are against the interests of the people.
HK, here I come to liberate thee..
Based on what you said - communism teaches a person on how to be a human being.
