> They did not have superior products, they had unique products (silk, tea, porcelain)
Those products were superior in their respective categories of textiles, beverages and tableware in the sense that wealthy Europeans preferred them over locally made goods.
> they realized there was something they should have bought. Technology.
Already the Ming dynasty had bought Portuguese cannons and were using them very effectively at first against the invading Jurchens. Of course then the Jurchens got their own cannons, conquered all of China and renamed themselves Manchu, establishing the Qing dynasty. They kept buying Western weapons, ships etc. over the following centuries. https://en.wikipedia.org/wiki/Military_of_the_Qing_dynasty#T...
However, it seems they didn't improve much on the bought technology, or didn't build up high enough production capacity. The British had started experimenting with adding steam engines to their sailboats in time for the First Opium War, which contributed to their defeat of the Chinese fleet (which included bought Western ships). If the Qing had put their energy into building an even larger fleet of steamboats, they might have been able to avoid a repeat of that defeat, but of course I have the benefit of hindsight.
