Cleaning up city is not without cost

It took workmen less than a day to tear down Yang Jun's restaurant, a business he had spent four years building.

The structure is among many razed as part of efforts to clean up Wenzhou, one of China's richest cities, in Zhejiang province.

In 2011, authorities launched a five-year plan to replace shabby or illegal properties with modern buildings and parks to improve living conditions and air quality.
