Do I need to provide technical parameters when applying for an invention patent?

1) Paragraph 3 of Article 26 of the Patent Law: The description shall give a clear and complete description of the invention or utility model, subject to the realization of the technical personnel in the technical field.

2) Paragraph 1 of Article 22 of the Patent Law: Inventions and utility models granted patent rights shall be novel, creative and practical.

So in a certain sense, you should also judge whether you need it according to the theme of the patent you are applying for. If you want to apply for a patent, it is recommended to apply through an agent. Otherwise, many things in the patent law are difficult for you to understand, and the application documents written are often far from your original intention, which may lead to little significance even if the scope of protection is finally authorized.
