Worldview begins with the final installment of the BBC's series, China's Long March. Since Mao's death in 1976, Communist ideology has lost much of its grip on the Chinese public. In its absense, many Chinese have been searching for alternatives to provide national cohesion. The BBC's Philip Short looks at how Chinese identity may shift in the next century. Then Worldview's film commentator Milos Stehlik looks back with Jiri Menzel, one of the leading directors of the Czech New Wave in the Sixties.
