Zhangjiakou, China

Capital City

At over 4.1 million residents, Zhangjiakou is a sprawling, windswept city in northwestern China with a harsh, continental climate. Situated above the North China Plain, the city's strategic position has made it a military stronghold for centuries, earning it the nickname "Beijing's Northern Door." However, the persistent bureaucracy and heavy red tape can be a headache for newcomers. With its abundant wind and solar resources, Zhangjiakou may appeal to those seeking green energy opportunities, but the rugged terrain and frigid winters make it a poor choice for the faint of heart.
