School shooting meme: Tibetans in rural China

Gansu province is a remote region in China — it's the part shaded in red in the map below. Snip from Radio Free Asia report:


Two senior Tibetan college officials have died following a shooting incident at a teacher training college in the Amdo region of China's remote Gansu province.
Separate sources confirmed the deaths of two top school officials in the shooting incident, at the Hezuo Teacher Training College in Kanlho (in Chinese, Gannan) prefecture during the college's 20th anniversary celebrations in late September, according to RFA's Tibetan service.

Lobsang, principal of the Hezuo Teacher Training College, shot Yang Zhihong, head of the school's Communist Party unit, killing him on the spot, the sources said, speaking on condition of anonymity. He then shot himself, and died later from gunshot wounds.

"It is true the incident took place. There were some disputes between these two local officers," a resident of the Amdo region said.
We don't know the reason for the shooting. There are no senior officials in the office right now due to a holiday(…)."
