==== Earliest geographical writing ==== In China, the earliest known geographical Chinese writing dates back to the 5th century BC, during the beginning of the Warring States (481–221 BC). This was the Yu Gong or Tribute of Yu chapter of the Shu Jing or Book of Documents. The book describes the traditional nine provinces, their kinds of soil, their characteristic products and economic goods, their tributary goods, their trades and vocations, their state revenues and agricultural systems, and the various rivers and lakes listed and placed accordingly. The nine provinces in the time of this geographical work were very small in size compared to their modern Chinese counterparts. The Yu Gong's descriptions pertain to areas of the Yellow River, the lower valleys of the Yangzi, with the plain between them and the Shandong Peninsula, and to the west the most northern parts of the Wei River and the Han River were known (along with the southern parts of modern-day Shanxi).
==== Earliest known reference to a map (圖 tú) ==== The oldest reference to a map in China comes from the 3rd century BC. This was the event of 227 BC where Crown Prince Dan of Yan had his assassin Jing Ke visit the court of the ruler of the State of Qin, who would become the first leader to unify China, Qin Shi Huang (r. 221–210 BC). Jing Ke was to present the ruler of Qin with a district map painted on a silk scroll, rolled up and held in a case where he hid his assassin's dagger. Handing to him the map of the designated territory was the first diplomatic act of submitting that district to Qin rule. Jing then tried and failed to kill him. From then on, maps were frequently mentioned in Chinese sources.
==== Han dynasty ====
The three Han dynasty maps found at Mawangdui differ from the earlier Qin State maps. While the Qin maps place the cardinal direction of north at the top of the map, the Han maps are orientated with the southern direction at the top. The Han maps are also more complex, since they cover a much larger area, employ a large number of well-designed map symbols, and include additional information on local military sites and the local population. The Han maps also note measured distances between certain places, but a formal graduated scale and rectangular grid system for maps would not be used—or at least described in full—until the 3rd century (see Pei Xiu below). Among the three maps found at Mawangdui was a small map representing the tomb area where it was found, a larger topographical map showing the Han's borders along the subordinate Kingdom of Changsha and the Nanyue kingdom (of northern Vietnam and parts of modern Guangdong and Guangxi), and a map which marks the positions of Han military garrisons that were employed in an attack against Nanyue in 181 BC. An early text that mentioned maps was the Rites of Zhou. Although attributed to the era of the Zhou dynasty, its first recorded appearance was in the libraries of Prince Liu De (c. 130 BC), and was compiled and commented on by Liu Xin in the 1st century AD. It outlined the use of maps that were made for governmental provinces and districts, principalities, frontier boundaries, and even pinpointed locations of ores and minerals for mining facilities. Upon the investiture of three of his sons as feudal princes in 117 BC, Emperor Wu of Han had maps of the entire empire submitted to him. From the 1st century AD onwards, official Chinese historical texts contained a geographical section (地理纪; Diliji), which was often an enormous compilation of changes in place-names and local administrative divisions controlled by the ruling dynasty, descriptions of mountain ranges, river systems, taxable products, etc. From the 5th century BC Shu Jing forward, Chinese geographical writing provided more concrete information and less legendary element. This example can be seen in the 4th chapter of the Huainanzi (Book of the Master of Huainan), compiled under the editorship of Prince Liu An in 139 BC during the Han dynasty (202 BC–202 AD). The chapter gave general descriptions of topography in a systematic fashion, given visual aids by the use of maps (di tu) due to the efforts of Liu An and his associate Zuo Wu. In Chang Chu's Hua Yang Guo Chi ("Historical Geography of Sichuan") of 347, not only rivers, trade routes, and various tribes were described, but it also wrote of a 'Ba June Tu Jing' ("Map of Sichuan"), which had been made much earlier in 150. Local mapmaking such as the one of Sichuan mentioned above, became a widespread tradition of Chinese geographical works by the 6th century, as noted in the bibliography of the Sui Shu. It is during this time of the Southern and Northern Dynasties that the Liang dynasty (502–557) cartographers also began carving maps into stone steles (alongside the maps already drawn and painted on paper and silk).
