What are some ideologically engaging places to visit on a trip in China? For better or for worse red tourism there seems particularly developed and commodified - I'm looking forward to seeing the contrast to eastern europe red historical sites, where post-communist states either tear it all down(Ukraine), fail to maintain it (Bosnia), or worse of all give it a lib rebranding as some kind of solemn commemoration to a dark age(Czech)
Are there any red themed sites you have enjoyed visiting or are looking to visit? Tours or accommodation recommendations are also very welcome.
Beijing and Yan'an seem to be a great start, with plenty of museums and art installations.
