Use a trademark similar to the registered trademark of others on the same commodity; 3. Use the same trademark as the registered trademark of others on similar goods; 4. Use a trademark similar to the registered trademark of others on similar goods.

(2) selling goods that infringe upon the exclusive right to use a registered trademark. (3) Forging or manufacturing others' registered trademark logo without authorization or selling forged or unauthorized registered trademark logo.
