Which huge ships?
Zheng He

There is a debate on the actual size of the ships, but at the time of the fleet, there was nothing close to it. It would be hundreds of years for another fleet to ever get as big as the treasure fleet of Zheng He.
Pretty amazing. Sadly, the Confucius isolationist took over China and they went from being a super power to forgotten.
