How i can find muslim food and mosque? is there available any muslim/hui restaurant in Changsha?

Yes, there are muslim restaurants in the city and the university has muslim restaurant, too, so please do not worry about eating problem.
Changsha Mosque is at No. 115, Sanxing Street, Xi District.

Thanks! since your Muslim and Hunan University mind if you share information about prayers. Is there any Musollah at university? How about Friday prayers? and is there Muslim student Associations at Hunan University. We all will celebrating AidilAdha at there, so how about the celebration in CS city. Kindly for your feedback.

Yes, there may be some Musollah in the university. Upon your joining in the school, you can turn to your classmates to find them. However, they may not have the Muslim Association. In spite of that, the university would hold some activities to help to Muslim students to celebrate AidilAdha. Don't worry!
