These works related to the institutional violence and sex racism in China. The idea about ‘leg gun’ started from Chinese Communist Party theatre pieces. The director wishes to narrate the war in the early 20th century in China by choreography. The scene shows females using their legs to simulating "Shooting" posture. This action not only symbolizing so-called ‘revolutionary spirit’ but also have the highly sexual hint (because of female diverging their legs). Therefore, I took this gesture into the Chinese Communist Party's propaganda posters (mostly during the middle of 20th century). The guns on the poster be replaced with my legs (male’s leg).
