Lanzhou, China

Capital City

With over 4 million residents, Lanzhou is a sprawling industrial hub in China's northwest. The city's strategic location at the heart of the ancient Silk Road has made it a major transportation and manufacturing center, but this comes at a cost - Lanzhou has struggled for years with severe air pollution, once ranking among the world's most polluted cities. Winters are brutally cold and dry, while summers are sweltering. Navigating the bureaucracy can be a persistent headache. However, Lanzhou's universities, museums, and natural scenery provide cultural and recreational outlets. This gritty, hardworking city may appeal to those seeking an authentic Chinese experience, but the environmental and logistical challenges make it a poor fit for the average expat.
