fifty seals. one bag. one night in beijing.   at the summer palace hotel, 50 friends from china’s culture, art and music scenes each stamped a personal mark onto the new siren — a nod to 印 (yìn), the chinese seal carved for centuries to mark identity and trust. a bag, made by many.   with @chacesound, @liuxuanchengisme, @6____ghost , @zhangyuxi281, @miakong999, @luoyangggg and friends.
