Zhongshan Memorial Hall, octagonal palace-style buildings, roofs are all blue glazed tiles, architectural style and Nanjing Zhongshan Mausoleum, with a strong national style. The Memorial Square is full of green grass, and a pair of granite-carved cloud crane watches stand on both sides, which is extraordinarily magnificent and solemn, quiet and solemn. Mr. Sun Yat-sen's handwriting "the world is the public" hanging high under the eaves of the memorial hall is vigorous and powerful. Walking into the memorial hall, you can see a huge portrait of Mr. Sun Yat-sen with bright eyes. The entrance of the memorial hall has explanatory service. My family and I hired a lecturer to follow her slowly and listen carefully to her story about the history of the memorial and the process of its construction.
