Introduction to the Mirror Grinding Platform: The Mirror Grinding Terrace is located in the central scenic spot of Nanyue Banshan Pavilion. It is named after Huairang, the seventh ancestor of China's Southern Zen, who polished bricks to make mirrors. Nowadays, there are stone carvings of "ancestral origin" preserved in the scenic area, which are said to be the place where Huairang polished mirrors. Huairang's tomb still exists today, and the contemporary Prime Minister Pei Xiu wrote "The Most Victorious Lun Pagoda" in his own handwriting. Mojingtai is a gathering place for humanities. During the Anti-Japanese War, Zhou Enlai and Ye Jianying held training courses for Nanyue guerrilla cadres here, and Chiang Kai-shek also held military meetings here several times.
