I worked in China in a very remote region on the Yangtze River in the fall/winter/spring of ‘76-’77. The peasant villages, buildings, and boats looked a lot like what you see in that painting. The main difference was that everybody wore Mao suits in that era.
What an incredible experience. It must have been major culture shock.
I assumed from college on that all of those landscapes were fantasy and just a style. Then I watched a movie on China and had my jaw drop at actually seeing the reality of those landscapes. WHAT a country! It’s like the Grand Canyon times 10.
