It is not recommended to operate in the gray area of intellectual property law and try to find the so-called "edge ball" method to sell adapted products. This involves many risks and may violate legal provisions, which will bring serious legal consequences to oneself. Intellectual property law aims to protect the legitimate rights and interests of right holders and clearly define the scope of rights and the boundaries of infringement. Any attempt to exploit loopholes and use gray areas is likely to constitute infringement. Once discovered, it may face serious consequences such as compensation for losses, legal liability, product removal, and damage to business reputation. To legally sell adapted products, authorization or permission should be obtained through formal and legal channels. Fully communicate and negotiate with the copyright owner, pay reasonable fees in accordance with legal provisions and contractual agreements, and obtain the right to legally use their works for adaptation and sales. Only in this way can we operate steadily within the legal framework, protect the legitimate rights and interests of ourselves and others, and maintain a good market order. Respecting intellectual property rights is the basis for promoting innovation and the healthy development of the cultural industry.
