Introduction to the top of the main hall: Not only is the interior of the main hall gorgeously decorated, the top is also unique. Visitors can see the five hexagonal roofs on the top of the temple connected into one when they climb up to a distance. A crescent moon stands on the top of the central building, shining brightly. The Five Summits are the "Five Mandates" believed in by Islam, which can be summarized as "recitation, etiquette, fasting, classes, and pilgrimage". They are the cornerstone of Islam's pious beliefs.
