Why does China believe in Islam?

Answer 1

China is actually majority Atheist or Shenist and the population of Muslims is less than 2% of the population, so to say that China "believes" in Islam, overshoots the mark. However, Islam is the majority religion of Xinjiang Autonomous Region and Ningxia Hui Autonomous Region and a well-represented religion in Qinghai and Gansu Provinces. It is popular in these regions because the Turkic Muslim Armies conquered these areas in the Battle of Talas against the Tang Chinese in 750 C.E. and were the predominant power in the region until 1755, when the Qing Dynasty overpowered the Turkic peoples and took the region back. However, by this point, the almost the entire population had become Muslims.
