What enlightenment does "One Man's Martial Arts" bring us?

2. One person’s martial arts world illustrates the insanity of Feng Yuxiu, played by Wang Baoqiang, who is addicted to his own spiritual world and cannot extricate himself. In order to practice martial arts, he could ignore his family, refuse to work, be willing to be poor, and remain indifferent to his wife who has cancer. In order to compete for the false reputation of being the best in the world of martial arts, he finally leads the road of destruction by killing his wife and killing others. Here, the martial arts fairy tale has turned into a martial arts tragedy, and Feng Yuxiu, who lives in the Huashan Sword Discourse, has been severely separated from real life. In order to better highlight his madness and cold-bloodedness, the director made his killing process strictly follow the rule of "first practice boxing, then legs, and then capture with weapons, from the inside out". And Feng Yuxiu killed innocent people for only one reason: Kung Fu is a killing technique. If two people compete, either you will die or I will live. As for the law in reality, that's another fairy tale that the killer sees no need to obey. "One person's martial arts world" was also said by Xia Houwu's junior sister Shan Ying: In your eyes, there is only your own martial arts world! She complained that Xia Houwu was also a martial arts fanatic and didn't understand the personal relationship between his children. Although Xia Houwu, played by Donnie Yen, was a master of martial arts and had a secret love for his junior sister, he stupidly didn't know how to express it. This made Shan Ying helpless and made Xia Houwu very entangled. However, in order to save his junior sister from being harmed by Feng Yuxiu, Xia Houwu could only use a small plan to join forces with the police to defeat the enemy. Therefore, a person's martial arts world is also a kind of obsession and solitary protection. "One person's martial arts" is out of tune with reality. No matter who it is, if they behave in the way of martial arts fairy tales and do evil in real life, they will be severely punished. You can "kill one person in ten steps and leave no name for thousands of miles" in the world of martial arts. You can enjoy your grudges and live your life freely without having to bear social and moral responsibilities, but this is not possible in reality.
