The wheelbarrow is believed to have been invented in China during the Han Dynasty in the 2nd century AD. A tomb mural found in Chengdu, Sichuan Province, shows a man pushing a wheelbarrow and is dated to 118 AD.
Fabriano in central Italy was the first European centre of paper-making, developed after 1296 CE. Miliani also introduced the watermark technique. The technology for pulping and pressing paper in this 15th century factory was not dissimilar to Chinese paper mills some 16 centuries earlier.
The Xiaotang Mountain Han Shrine (Chinese: 孝堂山汉墓祠; pinyin: Xiàotáng Shān Hàn Mù Cí) also known as the Guo Family Ancestral Hall (Chinese: 孝堂山郭氏墓石祠; pinyin: Xiàotángshān Guō Shì Mù Shí Cí, literally 'Xiaotang Mountain Guo Family Tomb Stone Ancestral Hall') is a funerary stone shrine from the early Eastern Han Dynasty (25-220 CE) situated on slopes of the Yellow River valley in the western part of Shandong Province, China.<br/><br/> An odometer for measuring distance was first described by Vitruvius around 27 and 23 BCE, although the actual inventor may have been Archimedes of Syracuse (c. 287 BC – c. 212 BCE) during the First Punic War.<br/><br/> The odometer was subsequently developed in ancient China, possibly by the profuse inventor and early scientist Zhang Heng (78 CE – 139 CE) of the Han Dynasty (202 BCE–220 CE). Zhang Heng is often accredited with the invention of the first odometer device in China. By the 3rd century (during the Three Kingdoms Period), the Chinese had termed the device as the 'jì lĭ gŭ chē' (記里鼓車), or 'li-recording drum carriage'.<br/><br/> Chinese texts of the 3rd century tell of the mechanical carriage's functions: As one li (c.500 metres) was traversed, a mechanical-driven wooden figure struck a drum, and when ten li was traversed, another wooden figure struck a gong or a bell with its mechanically-operated arm.
