Qiaonan Historical Street, located by previously Yanshui Harbor in Tainan City, is officially the first street in Yanshui District. Qiaonan Historical Street served as a key transportation hub from Yanshui to all southern towns in the Qing Dynasty. As time goes by, the street is no longer that important and vigorous, but the traditional street houses in this mixed-use historical street seem to well sustain. "Tingzijaio" is a bridge structure to connect a main house and the street shaping a single-layered eave. Qiaonan Historical Street witnesses the changing history of this area; there are still other spots worth of exploring, such as a one-hundred-year iron shop and Qiaonan coffee.
