How do the Wuyi Mountains affect travel between Fujian and inland China?

The Wuyi Mountains serve as a formidable natural barrier between Fujian and the interior of China, historically contributing to the province's isolation. These mountains, which reach elevations of approximately 6,000 feet (1,800 metres), act as a watershed between the Min River system in the southeast and the Gan River system to the northwest.1

Travel across this rugged terrain has traditionally been difficult due to the few, high, and challenging mountain passes. However, this isolation has been significantly mitigated by modern infrastructure:1

• Railways: The range is now traversed by multiple rail lines. The Xiamen-Yingtan railway, completed in 1957, crosses the mountains through Tieniu Pass, while a second main line completed in 1997 runs through Fenshui Pass to Nanping.23
• Highways: The construction of modern highways has further breached the province's traditional isolation, linking Fujian to neighboring Jiangxi and Zhejiang provinces.2
• Waterways: Historically, small boats navigated the headwaters of the Jin River up to the foot of the mountains to transport goods like tea.2
