Draw a clear line between the crime of copyright infringement and non-criminal acts, mainly based on the following two points: First, if the actor commits copyright infringement, but the amount of illegal income is not large or there are no other serious circumstances, his civil liability shall be investigated according to the general infringement, and he shall not be punished for copyright infringement. Only if the amount of illegal gains from infringement is large or there are other serious circumstances can a crime be established. Second, although the actor objectively violated the copyright, but subjectively there is no profit-making purpose, which does not constitute a crime and should be dealt with according to the legal responsibility stipulated in the Copyright Law of People's Republic of China (PRC).
