Geographical coordinates: Zhangzhou Prefecture, Jiulong River, Longxi County, Haicheng County (Yuegang), Zhangpu County, Pinghe County, Zhenhai Guard Do you believe that a single water management system could keep running for over 1,300 years? From 686 AD when Chen Yuanguang opened Zhangzhou, through 1573 AD when Luo Qingxiao compiled the Zhangzhou Fu Zhi, all the way to modern satellite remote sensing — the Jiulong River water network never stopped working. ...

Constant ethnic conflicts and primitive “slash-and-burn” farming kept the land in a state of barbarism. ...

Background: The “Energy Destiny” in a Mountainous Seascape Fujian, characterized by its “eight mountains, one water, and one field,” is a region where geography both restricted fossil fuel deposits and bestowed abundant hydropower and thermal resources. Throughout millennia, the utilization of “energy” by the Fujianese people has transitioned from wood and waterwheels to grand hydropower schemes and deep-crust geothermal exploration. As a senior historical researcher, cross-referencing digital archives from the Water Conservancy, Science & Technology, and Surveying & Mapping annals reveals an “energy geography” evolution curve. This is not merely a technical accumulation but an “energy gambit” of modernization. This article explores how Fujian utilized spatial surveying and modern finance to transform mountain-and-river advantages into the engine of industry. ...
