First of all, I want to know where you started. . . Generally speaking, the quickest way is of course to take a taxi. . If you don't want to take a taxi, you can also take bus No.3 from Rui 'an City to Shangcun, then walk south along the main road for about 300 meters, and you can see an obvious red street lamp, which is a relatively large intersection. At this time, your right hand position is the post office, and the second floor of the post office you mentioned should be Aoli Fitness. . . . Although I haven't been there either.
