The Chinese call it the Pink Mosque because the morning sun shines into the room through the stained glass windows, casting a beautiful pink hue on the entire mosque. Unfortunately, we went there in the summer, and the mosque opened at 8 a.m. When we entered at 8 a.m., the sun had risen too high, and the angle was wrong, so we could not see the pink color of the entire room, but only the beautiful shadows of the stained glass windows. You can only see pink in spring, autumn, and winter.
