Langzhong, China

The population of 622,667 may seem impressive, but Langzhong is no metropolis. This historic county-level city in northeastern Sichuan is dominated by low-lying mountains and hills, with a climate that features long, hot, humid summers and a mere 1,400 hours of annual sunshine. Bureaucracy is a persistent headache, as evidenced by the city's decades-long struggle to achieve county-level status. However, the well-preserved historic center, home to 30,000 residents, offers a glimpse into China's past and a respite from the crowds. Langzhong may appeal to those seeking a slower pace of life and a connection to traditional culture, but it's not for everyone.
