Timeline

  1. -200–220Guanzhong and the Central Plains · ShaanxiThe Han dynasty saw the appearance of the dragon-bone chain pump (fangche) and water-powered trip hammers and mills, using stream gradients to lift water for irrigation and process grain, establishing the basic types of Chinese water-powered machinery.
  2. 1011–1020Bianjing's outskirts and the Taihu Lake basin · JiangsuAround 1011–1020 CE, grain tribute processing near the Northern Song capital and irrigation of Jiangnan polders relied heavily on watermills, trip hammers, and chain pumps; official and private households jointly built water-powered workshops, boosting agricultural and artisanal productivity.
  3. 1021–1127Streams in the mountainous areas of Fujian and Sichuan · FujianIn the mid-to-late eleventh century, local gazetteers and agricultural treatises recorded various waterwheel designs and installation methods; large linked watermills were used for oil pressing, papermaking, and metallurgical bellows, making water-powered machinery an important component of Song productive forces.
