Tang (618-907) was China's most major dynasty.

That's debatable. I think the Ming Dynasty (1368 to 1644) was the most technologically advanced empire between the Roman and British empires. The Mings invented gunpowder, the printing press, global shipping, and the toothbrush(!) before the West did.

And it was most major.

Not just major, most major.

Like the most bestest.

Gunpowder predates the Ming by at least a couple of centuries. Mongols were using it in war by the middle 1200s.
