This performance-video work is the fruit of art workshops that Qingmei YAO  carried out with ULIS class students at the Collège Jean Wiener of Marne-la-Vallée in  France in 2020. Coordinated by the Orange Rouge association, the workshop was interrupted during the first lockdown and resumed when the college reopened. Group physical activities were suspended, and the workshop was redesigned to explore possible body movements in the college with "one meter of distance". Guided by performances and readings, this video goes out to meet teenagers, documenting and exploring the "dys-dancibility" of the body, showing a youth of incredible spontaneity and sensitivity despite social distance. Punctuated by the interplay between the measured and the measured, the video questions the contradiction between collective security and individual freedom.
