The etymology comes from the "Chasing the Deer in the Central Plains" in "Historical Records. Biography of the Marquis of Huaiyin", which was later cited in "The Romance of the Three Kingdoms" as "The heroes are fighting against the deer in the Central Plains." It means that heroes from all walks of life are fighting to seize the world. . This is also the reason why Mr. Jin Yong named The Deer and the Cauldron. The book mentions Kangxi, Obai, Tiandihui, Prince Zheng's Palace, Prince Mu's Palace, Wangwu Sect, Wu Sangui, Shenlong Sect, Russian Army, Mongolian Prince, and Tibetan Grand Lama. Everyone wants to compete for the world, compete in the Central Plains, and aspire to dominate the world, so they named it "The Deer and the Cauldron".
The mentions of Luding Mountain and Luding Gong in the book only echo the theme and have no practical significance.
