As mentioned by Big Lee, Haizi Shan is not any more unclimbed, since it was summited in October 2006 by British Malcolm Bass and New Zealander Pat Deavoll. Here again the link to the article.
The location is also missing from the page. Exact location is Lat 30°22'45"N Long 101°41'57"E.
For easier identification, the following names are interchangeable: Haizi Shan (or Haitzu Shang) is the Chinese name, while it is known in Tibetan as Mount Zhara Lhatse (aka Ala or Jara). The nearby town and monastery of Tagong (Chinese) is also known as Lhagang in Tibetan, while Kangding is Dartsedo (see some name reference here)
Zhara Lhatse is regarded since pre-buddhist tradition as an offspring of Nyenchen Tanglha, and is currently revered as one of the 25 Padmasambhava sites in East Tibet (Padmasambhava, aka Guru Rimpoche, is the 8th century Indian master who contributed to the first diffusion of Buddhism in Tibet).
Besides its holy status, Zhara Lhatse is also member of the exclusive club of the “Ultra Peaks” in the world that have a prominence above 1500m (approx. 5000ft). Its prominence is 1579m, with a saddle at 4241m connecting with its higher neighbour Minya Konka (7556m), located around 90km S-SE.
