Take the Subway Line 9 to Songjiang University Town Station, then transfer to bus 15 and get off at Guangfulin Road Sanxin North Road Station. After getting off, walk towards the No. 2 entrance of Guangfulin郊野 Park, which is about a 10-minute walk. Once you enter the No. 2 entrance, turn left and you will see the Rose Corridor. Look for a bench surrounded by roses within the corridor area.
(Note: "郊野" is translated as "Suburban" in this context, so it should be "Guangfulin Suburban Park.")
