Ask someone who knows the law. Do I find some funny jokes from the internet, post them on my own website, record them and publish them? Is it infringement or something?

First, the funny jokes circulating on the Internet are original and belong to literary works protected by law. Sending it to the Internet without permission is an act that infringes on the right to disseminate the information of the work on the Internet, except that the protection period of the property right of the work has expired.

Second, according to the provisions of Article 22 of the Copyright Law, performing works that others have made public for free is a fair use and does not constitute infringement.
