I second scarmig's recommendation of Bill Bishop's blog, it's a great resource and he publishes free pieces regularly so you don't need to subscribe. Another great free resources is the sinica podcast. I also recommend following Dan Wang's blog, he works at Gavekal Dragonomics and generally writes in-depth about manufacturing and the semiconductor industry in China, but also China more broadly. His recent post at the end of the year might be a good start. 'Reading the China Dream' is another good source, mostly commenting on and making accessible Chinese intellectual debates.

Having reread this comment now I realize I would love a reading list like this for the United States too :D

https://sinocism.com/ is one of the better US sources.
