CHAOYANG CUN 02/15/2009
 

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. 

 
 

Chinese: 兰州空战纪念碑，潮阳山 Lánzhōu Kōngzhàn Jìniànbēi, Cháoyáng Shān 
Map: Here

Cháoyáng Shān (潮阳山) is the hill to the east of Baita Shan. At the top, overlooking the Yellow River, is a monument to the Soviet pilots who died during the air battles of Lanzhou during the Second Sino-Japanese War (1937-1941). Take the back road to Baita Shan but go straight on at the gate, and follow the road up to the top.
 
 

There is a route up Baita Shan that takes you along the perimeter of the park itself, and brings you out on the road behind. Look for the steps that lead up to the mosque, to the right of the park entrance. As you climb, Chaoyang Shan is the hillside to the east. Map here.

 
BAOLONG SHAN 02/14/2009
 
Map here

Bàolóng Shān (抱龙山) is in Anning District, on the north side of the river, near the Qilihe Bridge. The route up starts from the north side of the road at Xìngfú Xiàng (幸福巷) bus stop (buses # 3, 103, 72). Walk up the small road, until you reach a 90 degree left turn. In the first picture below, don't go straight on (it becomes a dead-end). Follow the road to the left, and stay on the road until it ends, at the foot of the hills.

I stumbled across the website of Rolf Gross the other day, which has an incredible selection of photo-diaries, travel writing, and assorted essays. What caught my interest particularly was his description of a visit to Lanzhou in 1983.

The first photo on the page is of a sick child being wheeled along on a pushcart, with a mosque in the background. At first glance, I was pretty sure that I knew which mosque it was, and we confirmed this through a short correspondence, and by cross-referencing Rolf's route that day (along the north bank of the river upstream from Zhongshan Bridge) to another online photo. 

Rolf has given me permission to republish his photo of the 'Waterside Mosque' (水上清真寺) here. The photo was taken facing west, which means Rolf was standing midway between Zhongshan Bridge and the mosque:
