Tian'anmen, a variety show with 3-D technologies and displays of Beijing changing over the past 3,000 years, will be on stage in the National Stadium, or the Bird's Nest, until May 18.

The show, divided into four chapters, depicts the lives of local people in chronological order and highlights the dramatic changes in Beijing.
