In the area of automatic machinery, China was far ahead of the West during the Han dynasty with achievements such as the improved jacquard-type loom (developed by the wife of Chen Baoguang), Zhang Heng's seismograph, and Su Song's water-driven astronomical clock.
在自動機械方面，漢朝的陳寶光之妻改良了提花織機、張衡發明瞭候風地動儀、蘇頌發明瞭水運儀象台，都遠遠超越西方。
