The Red Folding Paper is located at the core section of Sanlihe Greenway, a linear space running north to south, which is about 700-m long and covers an area of 12 hectares. The site used to be a 10-meter-wide canalized river with concrete embankment. The river has gone dry for several years, with willows more than 10 years old thriving on both sides. The linear-shaped site separates the urban residential area from the peripheral rural area, with high-density urban residential area on the west side and an elementary school (the Fourth Experimental Primary School of Qian'an) and a kindergarten on the southeast side.
