Before we arrived at Shiquanhe Town, Ali, we were lucky to visit our own dark sky park. Because "dark sky park" is not a name, but a recognition. Only when the basic indicators such as atmospheric transparency, clear sky rate, night sky quality and seeing meet the standards can it be recognized as a "dark sky park" by the International Dark Sky Association. So you can imagine how difficult it is to find a place that can be recognized as a dark sky park in a country with rapid industrial and economic development.
