The magical power of Nandi Beggars in Time Has Changed appeared in two works by Mr. Jin Yong, Legend of the Condor Heroes and The Condor Heroes. The background is that at that time, the martial arts masters in the world held the "Huashan on Sword". In the "Huashan Argument on Sword", the masters of all major sects are vying for the "Nine Yin True Classics", and finally only five top masters are left, namely, Huang, Hong Qigong, Ouyang Feng and Yi Deng. Later, according to the characteristics of these five people, the Wulin people gave them nicknames, that is, the avatar of time ashes, Nandi Beigai.

Among them, Wang Zhongyang has the highest martial arts, and is called Wang Zhongyang because he founded Chongyang Palace. Because the Chongyang Palace was in the middle of the Song Dynasty, and Wang Zhongyang was the hero of the "Nine Yin True Classics", everyone called him "Zhong Shentong". However, in Mr. Jin Yong's works, only his name was heard, but he was not seen. The evil ghost is Huang, and Huang is the owner of Peach Blossom Island. He is proficient in medicine and temperament. Because he is a martial arts expert with both good and evil, people in the martial arts have nicknamed him "evil spirit".

Du is talking about Ouyang Feng, and Ouyang Feng made his debut in the Western Regions. Because he is vicious and good at using poison, Hong Qigong also called him "old poison", and Jianghu people nicknamed him "poison". Nandi is the first-class master of Dali Kingdom. Master Yi Deng was originally the emperor of Dali, but in order to practice Buddhism, he resolutely gave up the throne, so people in Wulin called him "Nandi", and his one-yang finger is said to be the bane of Ouyang Feng's frog skill. North Beggars are talking about Hong Qigong, the leader of Beggars' Sect. Hong Qigong is an expert in this field. Because he is a beggar, people in Wulin call him "North Beggar".

Of course, these are the results of Huashan's first sword discussion. Later, Wang Zhongyang disappeared and Hong Qigong and Ouyang Feng died. The second time Huashan talked about swords, he also named the new "Five Musts" at that time, namely, the east evil and the west mad monk and the urchin in the northern Xia, namely, the east evil Huang, the west mad Yang Guo, the south monk Eden, the northern Xia Guo Jing and the middle urchin Zhou. This is what everyone calls the "five wonders" of the two generations.
