Weihai, China

With a population of 2,906,548, Weihai is a major commercial port and fishing hub in China's Shandong province. The city has a strong industrial base, but foreigners should brace for persistent bureaucratic headaches. Weihai's coastal location brings a milder climate than inland areas, but also high winds - the average temperature variation is just 6.5°C throughout the year. While the city has cultivated close ties with South Korea, its remote northeastern location and heavy industry make it best suited for seasoned China expats rather than newcomers.
