Legal analysis: There is no relevant legal provision that prohibits theft of support slogans. Support slogans are just slogans used by fans to support celebrities. They have neither registered trademarks nor applied for patents, so they do not count. But it’s best to create your own as much as possible.
Legal basis: "Decision of the Standing Committee of the National People's Congress on Amending the Trademark Law of the People's Republic of China" 36. Article 38 is changed to Article 52, Item (1) is revised to read: "(1) Using the same or similar trademark on the same or similar goods without the permission of the trademark registrant"; Item (2) is revised to: "( 2) Selling goods that infringe the exclusive right to use a registered trademark"; add one item as item (4): "Replace the registered trademark without the consent of the trademark registrant and put the goods with the changed trademark back into the market."
