Art zones function as sculpture factories

Zhang Bao, a craftsman from Hebei province, works on a giant horse sculpture in Beijing's Heiqiao art zone.

The sculptures will consume eight tons of clay. The final process will be to cast copper on the surface after the clay work is done.

Beijing is a major hub where thousands of sculptures are assembled in "art zones". Most are in abandoned factories and suburban villages, such as Heiqiao, 798 art zone and Songzhuang village.

China's urbanization has sparked demand for urban sculpture. Major clients include local governments, the tourism industry and real-estate developers who want to attract and impress customers.

A father of two, Zhang has a no-job-too-small approach to his work, from an 18-meter-tall statue to small Angry Birds models. He can make 200,000 yuan ($32,600) in a good year.

Zhang says a worker on his team earns about 7,000-10,000 yuan a month - more than many white-collar jobs pay in Beijing.

But since last year the business has slowed. The anti-graft campaign, launched by the central government, has meant some industries that profited from abuses of public money have been affected, including the sculpture makers.
