This is a installation about social distancing during the Covid-19 pandemic, inspired by curtains and the traditional art of "Quipu" – knotted ropes. During lockdown, people are isolated at home, interacting with the outside world is like having to cross a barrier, different levels of social policy represent the degree of freedom of going outside, I took data from the first lockdown in Wuhan and London to visualize, and when people pass by them separately and will feel the difference between expereinces of lock-downs in each place.
