The only proper documentary series on ancient Chinese history can only be “If History is a Bunch of Meow” which has English subtitles and depicts the dynastic story of Imperial China, except if the emperors were instead animated cats. It’s currently covered up to the 10th century.

For a more serious narrative, Professor Ken Hammond of New Mexico State University, a comrade from PSL’s Albuquerque chapter who just recently published his superb book “China’s Revolution and the Quest for a Socialist Future,” did a “The Great Courses” lecture series on Chinese history back in the 2000s titled “From Yao to Mao: 5000 Years of Chinese History.” They’re available as an audiobook from Audible and also on sites like AudiobookBay.
