A report in AAJ 2005 about a British expedition's climbs in the Daxue Shan area mistakenly described the team attempting “Xiao Pangwa” and neighboring “Da Pangwa,” which in fact were Melcyr Shan and Peak 5,630m. (Neither of the names used by the British team exists on maps.) From a relatively low altitude in the upper Nanmenguan Valley, the team mistook the much larger summits of Jiazi (the 6,540m main summit and the south top) for 5,910m Melcyr Shan (known locally as Queba) and the (unnamed on maps) 5,630m peak to the south. The 750m snow couloir that they reported climbing faces southeast and rises to the east-southeast ridge of Jiazi, which it meets at around 5,500m. The British team descended from around this point.

In 2017, two Italian climbers summited Jiazi by the east-southeast ridge, approaching via the glaciated south face. They reached the east-southeast ridge just above the exit of the 750m couloir that was climbed to the ridge in 2004 (AAJ 2018).
