Nantong offers lessons for modern city planners

Nantong, Jiangsu province, is a special place to city planners.

An enterprising man named Zhang Jian planned the city, encircled by a 10-km moat, a century ago. The city has since expanded far beyond the moat, and the "old city" has actually become the "inner city" of today's Nantong.

Zhang's city planning influenced not only construction but also residents' views on life.
