Introduction to the Chakravartin Sutra: Located in the Huayan Hall, it is 11 meters high, 7 meters in diameter, and divided into 7 floors. It looks like a seven-level pagoda and is ingenious. Buddhism believes that turning it in a circle is like reciting the "six-character" mantra once, which can avoid disasters and prolong life. It has a complex structure, unique production, exquisite craftsmanship, and complicated carvings. The various statues of gods, wood carvings, and paintings on the body, as well as Buddhist classics, all have high historical and artistic value. It is the best preserved one in China.
