Sounds fake to me. Any actual Chinese to confirm this? Just going by the "they believe in the welfare state that “benefits only the idle and the free riders”" comment; China is a communist country, its about as far on the spectrum left past welfare state as you can go.
You can reach a higher level of understanding if you stop trying to cram multi-dimensional politics into a one-dimensional spectrum.
China is State Capitalist, not Communist. The government doesn't tell people what jobs to do and provide them with their home, food, and consumer goods
Yes, and the standard Communist criticism of the idea of welfare states (which, IIRC, predates both the actual existence of welfare states and also that of Leninism, much less the present Chinese Communist regime) is that it is a bourgeois “reform” to capitalism that provides the illusion of serving the lord classes but only actually reinforced the power and position of the capitalist elites.
(This is structurally similar to the right-wing capitalist criticism of welfare states, which is basically the same but substitutes an amorphousus government elite in place of the capitalist one.)
China is ruled by a party with "Communist" in its name, that's the only connection with communists. Officially China runs "socialism with chinese characteristics", but as other comments have pointed out, in realistic it's more like state capitalism.
And to answer your question -- yes it's a real word, and is used on Internet a lot. Literally it means white ("bai") liberals ("zuo" -- left).
