In brand marketing, trying to make competitors' products look inferior through improper means is unethical and may violate business standards. It is not worth advocating. This kind of behavior will not only destroy the fair environment for market competition, but may also cause serious consequences, including legal proceedings and reputational damage. Truly healthy and sustainable brand marketing should be based on positive ways to improve one's own brand value, product quality, service level, and unique brand positioning to win the market and consumers, and establish brand advantages through legitimate channels such as innovation, high-quality content, and excellent experience, rather than adopting marginal strategies that harm others and benefit oneself. Adhering to the principles of fair competition and honest management is the long-term way to build a good business ecosystem.
