Guan Yu and Jin Yong, a martial arts legend in Gu Long's novels. Martial arts moves explanation

Hello, everyone. As everyone knows, Jin Yong and Gu Long write martial arts novels. In my memory (from the 1980s), I have seen it before. The Legend of the Condor Heroes that I saw when I was young Laughing Proud in Jianghu 96 Lv Songxian Version The Condor Heroes, Ren Xian Qi Version Tianlong: The Chinese Version Heaven Sword and Dragon Sabre, Alec Su The following is an RPG game adapted from a novel: Jian Xia love Legend of the Moon Shadow .(These are from my memories. I have seen them and know them. Maybe I missed a lot) To get to the point, all the martial arts legends above: The martial arts that appeared in it, what eighteen Dragon subduing palms Nine Swords Beyond the Swords heaven and earth great shift Wait a minute... Wait a minute... For example, I remember that Hong Qigong and Guo Jing's Eighteen Dragon Subduing Palms (martial arts included in the plot) from the Legend of the Heavenly Sword and Dragon Sabre, which I saw when I was young. [For example, Nine Swords Beyond the Swords, from the Smiling Proud Jianghu (Feng Qingyang passed it to Linghu Chong)] [Senior Dugu and Nine Swords Beyond the Swords have also appeared in [Swordsman Kinship].] What I want to ask everyone is: Senior Dugu (name) Feng Qingyang Wait a minute... All kinds of characters and martial arts (For example, Nine Beyond the Swords, Eighteen Dragon Subduing Palms, Nine Yin Scripture, Nine Yang Scripture) Were they all Jin Yong's fantasies? This was because he really felt that the names of the martial arts commentators were too nice. He couldn't believe that they were completely written by the novel itself. Did the Nine Swords Beyond the Swords or the Eighteen Dragon Subduing Palms appear long ago in Chinese history? Then, the modern people would use this place to adapt their own novels? Take Taiji Zhang Sanfeng for example. With this person's Taiji Fist in reality, with the wisdom and wisdom of modern people, He had compiled many good television dramas and novels. I don't know if everyone can clarify the question I want to ask: It was simple: The martial arts of the characters I have mentioned above are purely fantasy novels. It had a real background and was then adapted. I want a detailed explanation. Thank you. It's best if you add your personal experience after giving me the information. Thank you, heroes! Also, I've been watching this a lot lately, and I've been dreaming a few times. I have already imagined a Wuxia character in my mind (Hehe, I also want to write a novel). I just want to ask everyone, if I write a novel and include some of the good martial arts of the Nine Swords Beyond the Swords, then the novel I write will be: Does it violate the copyright of others? Thank you again. If you want to laugh at me for being stupid, you can do so.(I accept criticism). If you want to scold me, you are the scum of China. You have no upbringing!
