The work summary is easy to write, just let your leader know you and reflect the value of your work. So write several points:

1. What have you done, concisely;

2. Which of these things require your personal skills to solve, or your personal brain to solve, so that the leader can see that you are working with your heart and brain. Even if there is no problem, you should also write about the difficult problems you encountered, and then solve them through your efforts, without burdening the company or bringing benefits;

3. Your understanding of the position and work through work;

4. What abilities do you need to improve in your future work or what knowledge do you need to supplement, and you have already started to do it and learn;

5. The boss likes people who are spontaneous, not people who are pushed. Therefore, you should be prepared to do the work that is not assigned to you but is your responsibility. You can write these points.
