Tian Shan 天山 (also known as Tengri Tagh or Tengir-Too) is a large system of mountain ranges in Western China and Central Asia (Kyrgyzstan, Kazakhstan, Uzbekistan, and Tajikistan)
Tian Shan is considered sacred in Tengrism, a religion originating in the Eurasian steppes. It was the prevailing religion of ancient nomadic groups like the Göktürks, Xianbei, Xiongnu, Mongolic peoples, and the Huns. As well as the state religion of several medieval states, such as the Turkic Khaganates and the Mongol Empire.
In Chinese mythology, it’s believed that Chinese gods dwell above Tian Shan when on heaven, and in Tian Shan when on Earth.
