Oh you're building production facilities to feed and cloth your people??? That's not very communist of you to not abolish the commodity form and wage labor.
Also countries are cringe, real communists don't need one. Stop building things!
For a longer history, I highly recommend CGTN's historic journey video series. It's a 20 or so part series (10 hours in all) that was created to celebrate the 70th anniversary of the CPC. It spans the entire history of modern China to the present day, and touches on all the lessons learned. It's very watchable and you'll go through all the important figures, periods, and struggles.
An extremely advanced but thorough book (i'm about 70% done with it), is Jin Huiming's - Marxism and Socialism with Chinese characteristics.
I haven't read these yet, but Edgar Snow's red star over china, and anna louise strong's the rise of the chinese people's communes document different periods while they were happening, and have interviews with many of the leaders above.
Also good to read their source material, including Liu Shaoqi's how to be a good communist, the quotations of Mao Zedong, and Deng Xiaoping's selected works. These are all remarkably readable and insightful.
Why on earth would the PRC or any communist country "abolish production relations". History has shown that the most important task of any country that frees themselves from colonial oppression, is to build industry, and develop production to uplift their people out of poverty.
Ignoring this task and focusing on "abolishing the commodity form" is ultra-left/anarchist nonsense, trying to insert vague ideological statements instead of the objective material reality and tasks at hand. The PRC went through an entire historical period to learn from and reject this nonsense.
And the PRC is absolutely not capitalist: see here.
Get down to business, all of you! You will have capitalists beside you, including foreign capitalists, concessionaires and leaseholders. They will squeeze profits out of you amounting to hundreds per cent; they will enrich themselves, operating alongside of you. Let them. Meanwhile you will learn from them the business of running the economy, and only when you do that will you be able to build up a communist republic. Since we must necessarily learn quickly, any slackness in this respect is a serious crime. And we must undergo this training, this severe, stern and sometimes even cruel training, because we have no other way out.
There are fundamental differences between different production systems that we Marxists think are important enough to warrant distinction, even if they're both instances of class societies.
I have a feeling you'd digest something better in video:
Syncthing is very much alive.
