Introduction to the ancient battlefield of Yamen in the Song and Yuan Dynasties: The Yamen Naval Battle Cultural Tourism Area in the Song and Yuan Dynasties is located on the east bank of Yinzhou Lake, Gujing Town, Xinhui District, Jiangmen City. More than 700 years ago, this is where Lu Xiufu threw himself into the sea on his back with the Young Emperor of the Song Dynasty on his back. The scenic area covers an area of 198 acres. It is China's first tourist area with the theme of ancient naval warfare, China's largest antique warship, the world's largest ship anchor, China's largest white marble dragon-top imperial seal, and the only emperor in Guangdong Province. The former site of the imperial palace and the longest poetry stele gallery in Guangdong are the highlights, recreating the witness site of the major historical event of the replacement of the two feudal dynasties of the Song and Yuan Dynasties in my country.
