Do you need originality to be self-media?

Don't be original from the media, but if there are necessary quotations or reference materials, be sure to indicate the source. Generally speaking, if there are some articles or opinions that don't involve other people's copyrights and patents, you don't need to declare them to the original author before quoting them, but your creative achievements must indicate the source, author and explanation of the quoted materials in a conspicuous position in writing, such as "If the quotation from * * * * is infringing, please contact me to delete it."
