Many innovative technology are found in this humble Ancient Fu Chuan (Chinese Junk).
Quote from New World Encyclopedia.
Junks incorporated numerous technical advances in sail plan and hull designs that were later adopted in Western shipbuilding.
- The sails were rigged so that they could direct wind into each other, allowing the junks to sail into the wind and to travel in heavy winds and rough seas.
- Unlike the sails of a traditional square rigged ship, the sails of a junk can be moved inward, toward the long axis of the ship, allowing the junk to sail into the wind.
- The sails can also be easily reefed and adjusted for fullness, to accommodate various wind strengths.
- Multiple compartments were built in the hull, accessed by separate hatches and ladders, and similar in structure to the interior of a bamboo stem. These could be made watertight to slow flooding, but the front compartments often had “limber holes” that allowed water to enter and leave the compartment, helping to ballast the ship in rough waters.
- Junks employed stern-mounted rudders centuries before their adoption in the West, though the rudder, origin, form and construction was completely different.
- Around the thirteenth to the fifteenth centuries, many junks incorporated "fenestrated rudders" (rudders with holes in them), to lessen the force needed to direct the steering of the rudder. Leeboards and centerboards, used to stabilize the junk and to improve its capability to sail upwind, were adopted by Portuguese and Dutch ships around 1570.

Maybe in the past, now China has the world best research facilities. but as usual, you alway live in the past.The world is glad the US/Canada gave these superstar Tsinghua graduates the opportunity to make these breakthroughs when they could find any local research locations in China.

They must have believed that those two are the only researchers in China. so living in the past is not the only problem of yours.Well I'm glad your facilities finally upgraded in 2024...as they seem to have had no reason to go back in the last 10+ years despite being Chinese citizens and perpetually having to go through the headache of extending their work Visas to work in countries where they said "they didn't quite fit in".

You still think China has just these two researchers, lol, are you for real?Well don't you find it incredibly sad that these two unbelievably famous superstars of Tsinghua University could not find any work back in China until 2024? Think of all those who were not so famous and still waiting and waiting and waiting.
You still think China as just these two researchers, lol, are you for real?
