Resume doesn't need too many words, just highlight a few key points. Work experience is very important, such as your previous work performance and your specialty. If you are a student, you can reflect your grades, but it is really bad. Show what you have learned and master your skills. If you feel trouble, I'll tell you a trick. In fact, you can also find someone to do it online. I asked a team called Entertainment to do it before, and I found it very effective.
Resume should generally include the following aspects:
(1) Personal data: name, gender, date of birth, home address, political views, etc.
(2) Academic content: schools, majors, etc. ;
(3) My experience: my experience since I entered school;
(4) Honors won; Miyoshi students, excellent league members, etc. ;
(5) My specialty: I have passed several levels of English and have an English grade certificate.
