Assalaamu alaikum [peace be to you],
In my first visit to the Niujie mosque in Beijing, China, I didn't get the chance to visit the exhibition rooms because they were closed.
so I made sure to return the next day, by God's will. in order to take some photos.
here you can see the photos corner in the first exhibition hall.
