Academic style writing on pre and post communist revolution China, with some first person narratives/interviews of workers. some interesting insights on how and why organized movements came to be and what is on the horizon for workers.
I'm sympathetic to their political orientation, but often found myself annoyed at their methodological stances, eg. non-mode of production thesis, China was not a nation, identification of the Chinese proletariat under socialism solely with "proto-proletarian temporaries, rusticates, apprentices and worker-peasants," and some other things that seemed straight out of the Endnotes Collective. These might be bold and useful, but often felt half-baked.
I also thought that they emphasized economic aspects too much — I'd have preferred more political history. They tended towards a vulgar materialism that viewed all political struggle within the party as a mere "epiphenomenon" to the economic developments. These economic developments then were viewed as both contingent (not following necessarily from any teleology) but also deterministic, not influenced by party ideology.
I do think that the heavy description of economic stratification, rural/urban divides, gender & seniority-based privileges, informal vs formal labor recruitment, is very valuable, although almost more as a suggestion for what we ought to be investigating about the present-day than for what it says about China. Pretty hard to use their writing-style for the present, though, since it relied on so much retrospective economic data not available to actors at the time.
