Introduction to the main body of the memorial hall: The Sun Yat-sen Memorial Hall covers an area of about 3,700 square meters. It is composed of four palace-style buildings with double eaves, resting hills and buildings on the front, back, left and right, like a four-layered dragon's spine, forming a whole. The arches support the huge octagonal pointed roof in the center. The whole building is not only majestic and resplendent, but also very rich in national style.
