But it protects the copyright and cannot prevent others from changing the specific expression.
postscript
Pure intellectual activity can't be patented in China, but it may be authorized if it can be combined with some network application technologies.
Answers to supplementary questions:
1. If your creativity refers to the layout of the website page, you should register the copyright, so as to prevent others from copying. Note that it is plagiarism, and it is generally not infringing.
If your idea involves network application technology or even software, you should register the copyright of computer software. If it involves software and emphasizes practical functions, you can apply for a patent.
Add one more thing:
With regard to copyright, China, like most countries, automatically generates copyright with the completion of works creation, that is, there is no need to go through any registration procedures.
Registration with the copyright office is only to add a hard evidence, which should be understood as such.
For patents, China adopts the first application system, that is, the applicant obtains the exclusive right first, not the inventor first. (The United States adopts the first invention system)
