Most people will say it's junk and I'll have to agree.
Genius is subjective.
It’s a beautiful ship & one like it might have carried the technology for wheeled toys from the orient to the “New World”.
Zheng He’s fleet, and the ships in it, were on a scale that wasn’t matched until the 20th century. There are populations of Chinese ancestry on African islands from one of his ships that wrecked. His voyages put Marco Polo to shame, and some folks believe he even reached the New World.
The Ming government ordered his ships burned and his records destroyed in the belief that China had all the wisdom the world had to offer and all this running around was a waste of time. Which leads to an important point: The critical prerequisite for discovery is curiosity.
