Two themes connect the stories in the six-episode documentary-one is the timeline and the other focuses on the development of Zhongguancun, from independent innovation centers there to market reforms and international cooperation.

"The significance of Zhongguancun is to show how science and technology is the primary productive force, and the importance of fundamental research and talent training," says Liu.

One of Liu's interviewees says in the film that Zhongguancun is a top hub of scientific and technological innovation.

Liu says the people in Zhongguancun "live in the future".

"Our discussion about the significance of Zhongguancun is actually exploring the future," Liu adds.
