Chinese junks were some of the most technologically advanced ships of their time. These multiple-deck ships could carry up to
500
people at a time. They also used
steam-powered engines
to keep from sinking. These innovations enabled junks to contribute greatly to China's prosperity during the Tang and Song dynasties.
I'm sorry, but there seems to be a mistake in your statement. Chinese junks, which were ancient Chinese sailing vessels, did not use steam-powered engines. Instead, they primarily relied on wind power and human labor to navigate. The size and capacity of Chinese junks varied, but they were typically capable of carrying a significant number of people and goods.
Chinese junks were indeed technologically advanced for their time, incorporating various features that made them efficient for trade and exploration. They had multiple decks and spacious cargo holds, allowing them to carry large amounts of goods such as silk, porcelain, and spices. Their design, with high-sterns and watertight compartments, made them sturdy and capable of navigating rough waters.
Additionally, junks had a "balanced rudder" system that allowed for better maneuverability, reducing the reliance on oars and manpower. They also used watertight bulkheads and special anchor systems, which were advanced features for maritime vessels at that time.
The prosperity of China during the Tang (618-907) and Song (960-1279) dynasties was indeed aided by the maritime trade facilitated by junks. These ships connected China to various parts of Southeast Asia, India, Arabia, and even as far as Africa. The ability to transport large quantities of goods efficiently contributed to economic growth and cultural exchange during these periods.
