I want to know the answer to the following question:
Where is Mount Tangjia?
All the background I'm provided with is that "The most precarious of these quake-lakes was the one located in the extremely difficult terrain at Mount Tangjia in Beichuan County, Sichuan, accessible only by foot or air; an Mi-26T heavy lift helicopter belonging to the China Flying Dragon Special Aviation Company was used to bring heavy earthmoving tractors to the affected location.". Is that enough to answer the question?
Answer: yes
