Yang Fudong regularly makes use of characteristic film genres. For example, City Lights is a mixture of the detective film and slapstick. A young, well-dressed office clerk and his Doppelgänger move in unison along the street and around the office. Like pre-programmed robots they fit perfectly into their apparently ideally organised environment. The day is entirely dominated by work, but the evening provides space for dreams and creative thinking, allowing a schizophrenic situation to arise. In their heroic conduct the two gentlemen sometimes develop into two gangsters who engage in a form of shadowboxing.
