Borrowing another person's work for a second creation and then using it for commercial use, if the second creation is the same or similar to the original work and has not been authorized or approved by the owner of the original work, it may constitute an copyright violation. This is because according to the copyright law, without the permission of the copyright owner, no one can copy, distribute, perform, show, broadcast, information network transmission, etc. to use the works of others. If the second work is the same or similar to the original work and has not been authorized or approved by the owner of the original work, then the second work is regarded as an extension or variation of the original work. Its commercial use is also regarded as an violation of the copyright of the original work. Therefore, in order to avoid copyright violation in the second creation, it is necessary to strictly abide by the provisions of the copyright law and not violate the copyright of others. If you want to use someone else's work for a second creation and use it for commercial purposes, it's best to obtain the authorization of the original owner in advance or to recognize it to avoid copyright infringement.
