There is currently no accurate record of when Islam was actually introduced in Nanjing. But what is worth noting is that in the neighboring cities of Yangzhou and Zhenjiang there were Muslims. Nanjing earned itself the title “The Metropolis of Ten Dynasties” due to its positioning on the southern bank of the Yangtze River. There was an estimated population of 100,000 Muslims in Nanjing during the Yuan Dynasty.
There is a total of nine mosques in Nanjing some are located downtown and other in suburban areas. Jingjue mosque is one of the 8 famous mosques in southeast China, it was ordered to be built in conjunction with Xian Huajue mosque by the Emperor Hongwu of the Ming Dynasty in 1392 AD.
