“Do a simple google of chinese blast furnace, you’ll see I’m right.”
It’s quite clear that ancient Chinese blast furnaces(for the production of cast iron) was largely muscle powered and entirely fueled via charcoal from wood. The major limitations for industrialization and the real expansion of this technology was the lack of an exploitable, high energy fuel source and mechanical power(coal/coke and large scale water mills respectively).
Were there earlier designs for water powered furnaces? Sure, but they obviously did not become economically practical (along with the discovery of coal/coke in the 15th century) and regionally widespread until the late 17th/early 18th century. By your measure, just because the ancient Greeks had devised primitive toy steam engines and mechanical computers in the 2nd century BC, they should have industrialized first right?
They used coal by the 11th century: Ebrey, Patricia Buckley (1999), The Cambridge Illustrated History of China, Cambridge: Cambridge University Press, ISBN 052166991X (paperback).
The Manchu dynasty cut China off from outside contact. The Ming dynasty before it tried to create rural communities with little trade; a very rigid society. But it’s the Song Dynasty that shows the Chinese pullback from industrialization in around 1000 to 1100. They had incredible technology and structure, but they opted for social order over technological and technical progress.
