BBC documentary - This World: The Fastest Changing Place on Earth - Changes on a remote Chinese village in 6 years
This is not directly related to China defence but I think it is a good documentary. Carrie Gracie tracked 3 families from a poor remote village in Sichuan province and record their life changes in 6 years when the farming land was turned into a metropolitan area. It is about hope, frustration, anger, injustice, sacrifice, struggle and happiness for regular China farmers in the ages of China's rapid development. I always feel that regular people like farmers and migration workers are the biggest heroes whose sacrifice have contributed to China's progress and their children's better future. For this I solute them.
I think people who want to know what's really happening in China should watch this.
