Continuing someone else's work and copying the last chapter may constitute copyright violation. According to the copyright law, without the permission of the copyright owner, no one is allowed to copy, distribute, rent, exhibit, perform, show, broadcast, or spread the works of others through information networks. If he continued to write someone else's work and copied the last chapter, although it might constitute copyright violation, the specific situation still needed to be analyzed. For example, if the continuation is the same or similar to the original and does not violate the copyright of the original, it may be an copyright violation. However, the specific situation still needed to be confirmed by legal professionals. Therefore, in order to avoid any acts of copyright violation, authors should carefully consider respecting the original work and not directly copy the last chapter of other people's works.
