Socialism in China is already existing, just in a primary stage, rather than advanced.

Yes, I completely agree with you and have never denied that. I merely pointed out China's current shortcomings—issues that need to be addressed, rather than denied as if they didn't exist.

As production and distribution advances, private ownership will continue to be gradually appropriated and folded into the public sector, creating a fully planned economy.

Yes, the ultimate goal is clear to me as well.

Here’s Cheng Enfu’s diagram explaining it:

Yes, I have a rough idea—but, Comrade, I don't know English quite as well as I'd like. And Google doesn't translate tables...

I’m aware that the USSR had critique of Chinese socialism.

That’s putting it very mildly... The thawing of relations didn't begin until the Gorbachev era. Finally, the Chinese leadership liked what was happening in the USSR... ))) But in reality, it was all very simple: the USSR admitted defeat.

China also criticized Soviet socialism

(What was written in Smena magazine, February 1–3, 1967)

"Red Guards" (紅衛兵) Block the Way

"For the sixth day, the Soviet Embassy in Beijing has been besieged by frenzied mobs of Red Guards. Anti-Soviet speeches are being broadcast via loudspeakers. Announcers read out 'death sentences' issued by the Red Guards against embassy staff members. A welcoming ceremony for Chinese students arriving in Beijing—students who had participated in hooliganistic disturbances on Red Square in Moscow on January 25—was turned into an anti-Soviet demonstration. Speeches delivered at the event contained crude invective and calls for violent reprisals against Soviet citizens. On the streets, Soviet citizens—including diplomats leaving the embassy—are surrounded by crowds of Red Guards who block their path, hold them in place for hours on end, and subject them to humiliation, intimidation, and blackmail."

Mao Zedong Thought is the learned experience and theory from China’s specific socialist construction process.

...very specific, to put it mildly...

Functionally, the PRC remains a dictatorship of the proletariat.

This question should be directed at Ma—and at those who buy luxury cars. China is the global leader in luxury car purchases.

I’m curious: when China makes its full transition to socialism, what will become of all those cars, yachts, and villas? Or will every Chinese person be able to afford them? ... )))
