Introduction to Yangzhitang: In the second year of Jingyan, Duanzong of the Song Dynasty (1277), the Yuan army advanced by land and water and occupied the entire territory of Guangdong. At this time when the fate of the country is at stake and the building is about to collapse, people are distracted and each is looking for a way out. Lu Xiufu stepped forward, never gave up, and was loyal. Emperor Duanzong Zhao of the Song Dynasty suffered from fright and became ill due to a strong wind, and collapsed in the boat. Lu Xiufu and others supported King Guang Zhao Bing as emperor and continued to persevere in the struggle against the Yuan Dynasty. During his three-year reign, Lu Xiufu worked hard, strategized, raised military supplies from outside, and mobilized workers from within. He did everything he could to support the precarious Southern Song Dynasty regime.
