Tianshui

Tianshui is a prefecture-level city in Gansu province, China, and is the province's second-largest city (behind the provincial capital Lanzhou). Located in the southeast of the province, the city strides along the upper reaches of the Wei River and at the boundary of the Loess Plateau and the Qinling Mountains. As of the 2020 census, its population was 2,984,659 inhabitants, of which 1,212,791 lived in the built-up (or metro) area made of the 2 urban districts of Qinzhou and Maiji. The city and its surroundings have played an important role in the early history of China, as still visible in the form of historic sites such as the Maijishan Grottoes.

==History== Qin, whose House of Ying were the ruling family of the founding dynasty of Imperial China, developed from Quanqiu (present-day Lixian) to the south. After the invasions of the Rong which unseated the Western Zhou, Qin recovered the territory of Tianshui from the nomads. It became an important region of their duchy and, later, kingdom. Characteristically Qin tombs have been excavated at Fangmatan nearby, including one 2200-year-old map of Qin's Gui County.
