A maze was set up on Aug 5 in Beijing's Sanlitun area to promote film director Zhang Yang's art-house film Soul On A String, which will hit screens on Aug 10.

The film is about a Tibetan cowboy looking for a sacred stone.

In the maze, there are dancers, actors and soothsayers telling visitors which way to go.

A series of lectures and forums on the film will be held after it hits the screen.
