In August 2014, Ai Weiwei was invited as one of the participating artists for the Fukushima Nuclear Zone by the Japanese art coalition Chim↑Pom, as part of the project "Don't Follow the Wind". Ai accepted the invitation and sent his assistant Ma Yan to the exclusion zone in Japan to investigate the site. Ai brought about two projects, "A Ray of Hope" and "Family Album" after analyzing materials and information generated from the site.
