Industry: Tea
We know from written accounts that the Chinese have been drinking tea since at least 2700 B.C. For several thousand years, tea—made by letting tea leaves steep in boiling water—was drunk mostly as medicine. However, by the 8th century C.E., tea had become a hugely popular everyday beverage throughout China. -

Exploration and Travel: Paddleboat
Within China, people often traveled by boat on rivers or across lakes. An innovation of a vessel called a paddlewheel boat made this type of travel must faster. The Chinese came up with this idea by arranging a series of paddles in a wheel. People walked on a treadmill to turn the paddlewheel, which in turn moved through the water, moving the boat forward. -

Exploration and Travel: Canal lock
Before the improved locks were invented, the Chinese had to drag their boats up stone ramps to reach water at a higher level. This was difficult and could damage the boats. -

Exploration and Travel
In 618 C.E., a Chinese engineer completed a new type of arched bridge. In Europe, Roman-designed bridges rested on arches that were half-circles. The new Chinese bridge used arches that were a smaller part, or segment, of a circle. This made the bridges broader and flatter than semicircular arches could. Called a segmental arch bridge, the new type of bridge took less material to build and was stronger, as well. -

Military: Gunpowder
The Chinese who first made gunpowder were alchemists, people who practiced a blend of science and magic known as alchemy. Alchemists experimented with mixtures of natural ingredients, trying to find a substance that might allow people to live forever. They also searched for a way to make gold out of cheaper metals. -

Industry: Porcelain
Some historians think that the Chinese produced the first porcelain as early as the 1st century C.E. By the 10th century, the Chinese were making porcelain of great beauty. Crafts-people learned how to paint pictures on porcelain. They also made colored glazes to decorate their porcelain. Chinese porcelain became a prized item for trade. -

Industry: Printing Press
The invention of paper made another key development possible: printing. In about the 7th century, the Chinese invented a technique called woodblock printing. The printer first drew characters (symbols) on paper. He then glued the paper to a wooden block. When the glue was dry, the printer carved out the wood around the characters, leaving the characters raised on the wood. In the 11th century, during the Song dynasty, the Chinese invented movable type. -

Military: Bombs
In the 13th century, the Chinese used large bombs that were as explosive as modern bombs. Around the same time, they developed weapons much like today’s rifles and cannons. By the early 1300s, travelers had brought the knowledge of gunpowder to Europe. -

Military: Rockets
Rocket technology was developed in China during the Song dynasty. Rockets were powered by a black powder made of saltpeter, charcoal, and sulfur. At first, rockets were used only in fireworks. Later, the Chinese used them as weapons. They even developed a two-stage rocket for their armies. By 1300, rockets had spread through much of Asia and into Europe.
