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. Tea houses had sprung up throughout the country. -

The Compass
The Chinese developed the first compass as early as the 3rd century B.C.E. The first Chinese compasses were pieces of a magnetic mineral called lodestone. Earth itself is like a giant magnet with north and south poles. Because lodestone is magnetic, it is influenced by Earth’s magnetic poles. -

Printing
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. -

Mechanical Clock
The Chinese developed the first mechanical clock in about the 8th
century. The new clock was more accurate than earlier timekeeping devices, such as sundials and hourglasses. The Chinese devised a wheel that made one complete turn every 24 hours. Dripping water made the wheel turn. Every quarter hour, drums would beat; and every hour, a bell would chime. The sounds let people know what time it was. -

Paper Money
Paper money was invented by the Chinese in the late 8th or early 9th century. Before that time, coins were the only form of currency. Like game cards, paper money was printed with wood blocks. By 1107, Song printers were using multiple wood blocks to print each bill. A single bill would have many colors. Paper money is the most common form of currency in the world today. -

Disease Prevention
Chinese knowledge of medicine and disease prevention dates to ancient times. Before the 1st century C.E., the Chinese developed a way of fighting infectious diseases. An infectious disease is one that can spread from person to person. When a person died from an infectious disease, the Chinese burned a chemical that gave off a poisonous smoke. They believed that the smoke would destroy whatever was causing the disease.
