She, a mother of two, carried out her self-immolation around 4 am in front of a Chinese security and re-education building located within the compound of Choparshing monastery.
The monastery has been under intense pressure including arrests of monks and applying fines for having peaceful protests. The large buildings that house security and propaganda workers had been actually built inside the monastery's walled compound to watch activities of monks.
These suppressive actions of the Chinese authorities have deeply hurt and humiliated the local Tibetans who see them as attacks against Tibetan culture and religion, and that the sense of injustice and helplessness felt by many may have been what drove Sangye Tso to carry out her desperate protest.
