Chaoyang Cun (潮阳村) is the network of hutongs behind the City No.2 People's Hospital (市第二人民医院), to the east of Chaoyang Shan. I reached there by following the paths off the southeast of the hillside. Map here.
I departed from Chaoyang Cun by coming down these steps, and popping out onto Bei Binhe Lu (北滨河路) next to a halal butchers, just to the west of the hospital.
