Yong'an

Yong'an is a county-level city situated in the west-central region of Fujian province, People's Republic of China, specifically within the prefecture-level city of Sanming. Located along the Sha River, a major tributary of the Min River, it lies approximately 290 kilometers west of the provincial capital, Fuzhou. While the provided text does not describe a specific medieval fortress or traditional castle structure named Yong'an, the city itself holds significant historical stature as an administrative stronghold. It was elevated from a county to a county-level city in 1984 and served as the temporary capital of the Fujian Provincial Government during the Second Sino-Japanese War between 1938 and 1945, marking its importance as a political and strategic hub during a turbulent era in Chinese history.

The area is renowned for its exceptional natural environment and robust industrial development rather than ancient stone architecture. Often described by the local saying gold mountain silver water, Yong'an boasts a forest coverage rate exceeding eighty-five percent, a rare ecological feat for coastal southeastern China. This rich natural resource base has supported its transformation into a rising industrial center and a key provider of energy and raw materials within the province. The city maintains a population of roughly 319,000 people and serves as a cultural hub where the Central Min language, specifically the Yong'an dialect, is spoken. Today, Yong'an functions as a modern municipal entity that balances its legacy as a wartime capital with its current role as an economic engine driven by its abundant forestry and industrial sectors.
