Ganquan is a place name in China. The reference material provided concerns Ganquan County, a county in the north of Shaanxi province, which is under the administration of the prefecture-level city of Yan'an. That county covers an area of 2,276.1 square kilometres (878.8 square miles) and had a population of 77,800 as of 2012.
The source material does not describe a city named Ganquan in the Liaoning region of China, and no verified details about such a place are available here. Because the instructions call for writing specifically about a city in Liaoning rather than a more famous place sharing the name, and because the only supplied source concerns Shaanxi's Ganquan County, no factual description of a Liaoning city called Ganquan can be given on this basis.
Accordingly, this stub is limited to what the source supports: Ganquan County in northern Shaanxi, administered by Yan'an, with the area and 2012 population figures noted above. Any further claims about a Ganquan in Liaoning would go beyond the reference material and are therefore omitted.
