I did a bit of research about yangding monastery but unfortunately there isn't much information available in English. However, I did find this interesting excerpt about what may be yangding monastery:
Shonden Monastery
(12,400 feet and 10Km to the northeast of the township, Geluk Sect)
Originally it was a Kagyupa monastery.In 1415 a Geluk monk with the name of Lhodzui Lunje made a change. In the background of overwhelming Gelukpa in Tibetan areas it developed into the largest one in Daocheng.
Highlights: *No.1 Mani Pile
On the left of the monastery there is a huge Mani pile regarded as the first in Kham region
*Log Genitals
The locals believed there were a lot of ogresses in Daocheng and they would stir up trouble. Lamas in monasteries were responsible for getting rid of them. Avoiding killing any life lamas erected these log genitals, with which those fleshly and conquettish succubuses would be satisfied and made no trouble.
Also this interesting story that shows just what the attitude in the Tibetan communities loyal to shugden is like:
In one of the huts, I met an old man named Tenzin:
Tenzin had one peculiar thing in his hut: a picture of the deity Dorje Shugden. This god is very controversial in Tibetan Buddhist circles. Some religious authorities have suggested that it would be better not to worship Shugden, however the deity has many devout believers, both inside and outside Tibet, who have refused to give him up. In Xiangcheng, they are especially numerous. In fact, the whole county seems to be one hundred per cent believers in Shugden. The monastery overlooking the Xiangcheng County town, Ganden Shangpo Monastery, had a large gilt relief carving of Shugden inside. It is really a splendid monastery, with 800 monks and the finest interior furnishings I have ever seen in my travels in Kham.
My translator, a conventional sort, would have preferred not to talk to these Shugden people. Having explained to me once about Shugden, he thereafter referred to the deity in veiled, derisive tones as " that god." When he spotted the picture on Tenzin's table, he said, "there is a picture of - that god." He could not, however, explain to me what's the problem with Shugden. Since then, I have discovered a great deal of information, both for and against, on the Web. The curious reader should have no problem finding out more.
