Introduction to the main entrance of the main hall: There are many pottery dragons, owl kissing swallowing ridges, etc. on the roof of the main hall. In the center of the roof stands a 4.55-meter-long, five-section bronze gourd weighing 1,000 kilograms. There is a 1-meter-long, 300-kilogram-weighted gourd at each end. The bronze swords are not only treasures to suppress evil, but also act as lightning rods, adding a magnificent and magical color to the entire hall, and have been praised by many domestic and foreign experts in architecture and metallurgy. There are 72 stone pillars inside and outside the main hall, symbolizing the 72 peaks of Nanyue. Among them, the two pillars in front of the main entrance are hewn from a single piece of granite, with a height of 6 meters, a diameter of 1 meter, and a weight of 14 tons. They were taken from Hengshan Mountain in Nanyue.
