Karamay(2010)

In 1994, the oil-rich city of Karamay in Northwest China was the site of a horrible fire that killed nearly 300 schoolchildren. The students were performing for state officials and were told to stand by while the officials exited first. After the fire, the story was heavily censored in the Chinese state media. To this day, the families of Karamay have not been allowed to publicly mourn their children.
