Jinzhong

Jinzhong, formerly Yuci, is a prefecture-level city in east central Shanxi province of the People's Republic of China, bordering Hebei province to the east. As of the 2020 census, its total population was 3,379,498 inhabitants of whom 1,226,617 lived in the Yuci and Taigu urban districts. However, 5,433,659 lived in the built-up (or metro) area of Taiyuan - Jinzhong made of Yuci district plus the 6 Taiyuan urban districts, largely conurbated.[2] Lingshi County was the location of the Nanshan Colliery disaster. In 1999, the area was considered sufficiently urbanized that Jinzhong Prefecture became a prefecture-level city, with its former seat at Yuci becoming its county-level Yuci District.
