The Han Dynasty (206 BCE – 220 CE) is known for several significant inventions, including paper, the seismograph, and the rudder for ships. However, the compass, which is often associated with ancient Chinese innovations, was not invented until later, during the Song Dynasty (960–1279 CE). Thus, while the Han Dynasty made remarkable contributions to technology and science, the compass was not among their inventions.
