In pictures: Graffiti artists in Beijing

Graffiti is so accepted in the West it formed the basis of the new controversial logo for the London 2012 Olympics. In China too, which hosts the Olympics next year, graffiti has a long tradition.

It began with Mao Zedong in the 1920s who used revolutionary slogans and paintings in public places to galvanise the country's communist revolution.

Wang Mo, 24, is one of a new generation of Chinese graffiti artists using the art-form to comment on modern Chinese society.
