I have a friend who burned some CDs about the experience of fish farming and ornamental fish. At first, it was nothing more than 10 yuan. Later, it proved that the effect was not bad, so I made more. As a result, it was arrested by the Cultural Bureau, saying that it was pirated, and what else was burned privately and commercially? Equipment (that is, computers and tape recorders) was confiscated, and the illegal income was fined more than 5,000 yuan.
If you want to help others, you'd better go through formal procedures to register, and then register and apply, so there is no problem.
Remember, remember
How to apply should go to the Cultural Bureau for consultation. It shouldn't be long. I don't know about that. I just looked it up on the internet and said it was ambiguous. Go and consult yourself.
good luck
