“Buy more, get more” is a work triggered by the experience of working in Blackwood Gallery helping to prepare the Aero Solar project for The Work of Wind. When Anran Guo was helping to prepare the Aero Solar project, she was actually helping to cut hundreds or thousands of plastic bags into squares during the whole summer. she felt that whoever invent the way of charging 5 cents for each bag and think it is going to change the situation of the plastic waste issue is too “optimistic”, this will only raise the benefit of the store instead of decreasing plastic usage. Therefore, this piece is a response to criticize or mock the waste of and commercialization of plastic bag.
