“The world is not changing if you don’t shoulder the burden of responsibility.”

On May 12, 2008, the 2008 Sichuan earthquake hit the Sichuan region of China at a magnitude of 8.0. It is believed that over 68,712 people died, and over 18,500 were announced missing. These figures were not immediately released, causing Ai Weiwei to do a search on his own with volunteers, who asked parents to provide the name, birthday, and school of what they found were 5,212 student earthquake victims.

In the documentary, Ai says, “I write blog every day. Sometimes two articles a day. But for seven days during the earthquake I couldn’t write one blog. I just simply could not write. It is devastating. I’m speechless.”

Ai installed 9,000 backpacks at his 2009-2010 So Sorry exhibition at Haus der Kunst in memory of the children who were lost.
