Science and technology

The application of bamboo in science and technology is thrilling. The Chinese invented a bamboo drill dating back to the Shang Dynasty (1600-1100 BC). In 251 BC Li Bing, in Sichuan prefecture, led the local people in building the Dujiang Weirs, the first irrigation network in the world, in which bamboo played an important role. The world's oldest water pipe was also made from bamboo. During the Han Dynasty (206 BC-220 AD) the Sichuan people successfully sank a 1,600-meter-deep well with thick bamboo ropes. This technology did not spread to Europe until the 19th century, and in 1859 the Americans drilled the first oil well in Pennsylvania by using the technology.
