You are falling into the Eurocentric narrative trap.
Read history please!
A wealthy Chinese industrialist and merchant have several storage buildings to store their goods. It's not a small workshop, but a massive factory complex. You also need to search about Chinese water powered machinery too.
The reason why China missed steam engine, not because Chinese people was dumb, but at the time mass produced good by machine was not as good as made by hand. Chinese people at the time were wealthy enough to purchase hand made product.
Without China, there will be no British Industrial Revolution too, as modern economy model of Europe was a copy of Chinese economy model. From free market, good transportation to mass production. That gave British advantage over another European countries until the rise of Germany.
It's not true that China was just an AGRICULTURE civilization. China had a massive agriculture sector to feed their industrial sector and export on the Silk Road. Eurocentric historian just want to look one side of China, so they can claim the other industrial side of China as theirs.
