For different types of units, you should highlight your professional expertise in your resume.
Some employers may pay more attention to practical experience, so they should highlight practice and put it in a conspicuous position. Some employers may attach importance to the professional foundation, academic performance and other certificates of job seekers, which should be highlighted in their resumes.
In general, your resume should not exceed 3 pages. People don't have that much time to read your resume carefully. They only look at important places, such as your education or social practice.
I suggest two pages is the best, and the cover letter can be added to your resume.
