Hi Lisa .
Do you know Shang mao qu area ,the place with a lot of muslim resturant . I guess you know . There is one Xinjiang resturant named Muhammad resturant in front of one big internet club.and just on the left side. There is one retail shop for retail digital qur'an . In the market ,if you check carefully you can also find.But takes some time. It is in the phone accessary part . some shops sell one .
Good luck !
