Is there any Muslim in Weihei?

What is Weihei? Do you mean Weihai city? Yes, you will find Muslim in this city.

I am a resident of Yantai City in the north of Qingdao. I often travel between Weihai, Qingdao and Yantai. I have hardly seen Muslims for so many years.
Several cities on the Shandong Peninsula have few Muslims.
But you can easily find Muslims in some cities in Ningxia Hui Autonomous Region and Xinjiang Uygur Autonomous Region, where many residents believe in Islam.
