This morning, head on a leader-led walking tour to the Muslim Quarter, which features narrow streets of quaint shops, lively food markets and the life of Chinese Muslims. Then, enjoy some free time until your evening train. You can choose to visit the Bell Tower, which according to legend was built to restrain dragons that were causing earthquakes, or the Drum Tower, which is full of instruments once used to mark time and warn the population of emergencies. Or, explore the 13-km-long City Walls and attached Gates – you can rent a bike and cycle the whole loop. In the evening, board your second overnight train bound for Shanghai.
