Will be joining China Medical University this Summer. Brief detail bout muslims living in Shenynang?

You must refer to the campus located No. 92 Beier Malu?
If so, as I know, there are halal restaurants inside the university. You can have your dinners there.
There are Huanggu Mosque, located at No. 38 of Banping Shanlu, South Mosque, located at Fengtian Street, Shenhe District. You can go these two mosques.

The living condition in that city is actually good. The price of goods is not expensive, and income usually can meet the demands of expenditures. The air condition there is also fine.
