QJ 1358 and QJ 1360 were working flat out around the "S" curve north of Tianzhu when they were photographed on 30 December 1989. Since leaving the yard at Wuweinan, the pair had travelled 95 kilometers and climbed well over one kilometer vertically. After a brief stop for water and fire cleaning at Tianzhu, they would be ready to tackle the last 14 km to the summit.
