The buses from Zhang to Xuanhua don't go to Zhonglou, except for the 8th road. Or take other cars to Xuanhua (ground transportation, minibus), and then get off at Hezixi to take the 8 road from Hezixi to Ertaiji, to the bottom of the bell tower.
It seems that the car to Xuanhua does not go to the train station side, it should be directly to the bell tower.
