In Chinese, Shanzhai (山寨) literally means "mountain stronghold" and connotes a place with limited accessibility -- i.e. beyond the reach of authorities. In the past couple of years, it has come to refer to the manufacture of illicit tech gadgets by unauthorized factories: show us your shan zhai ji! But shanzhai can be used more broadly to describe knockoff culture, cheeky brand subversion, grassroots industrial creativity, and a certain DIY ethos.
