China has a million strong army, that means you see military facilites everywhere all cross this vast natioin, cities, towns, villages, mountains and seas..., that's what you need to have to hold 1 million people.
The only city with the resident urban population over 1 million in Xinjiang is Urumqi, a mega city in central Asia, now the western media claims that China holds 1 million Uighurs, one tenth of their whole population, including babies, children and the very old in concentration camps... before they said that, did they even spend a second to think of a simple question, where does China get those facilities in Xinjiang province for those so called 1 million people? Stupidity at the finest.
