  Joseph Needham suggests that certain pottery vessels of the Han dynasty (202 BC – 220 AD) showing artificial mountains as lid decorations may have influenced the development of the raised-relief map in China. The Han dynasty general Ma Yuan (14 BC – 49 AD) is recorded as having made a raised-relief map of valleys and mountains in a rice-constructed model of 32 AD. Shen Kuo's largest atlas included twenty three maps of China and foreign regions that were drawn at a uniform scale of 1:900,000. Shen also created a raised-relief map using sawdust, wood, beeswax, and wheat paste. Zhu Xi (1130–1200) was inspired by the raised-relief map of Huang Shang and so made his own portable map made of wood and clay which could be folded up from eight hinged pieces.
