The number of words in the paper is not enough, so we can start from the following aspects: literature review, theoretical basis, body part and thesis outline.

Literature review is the best part of collecting words. It can be said that there is no pressure to put together a few hundred words casually. As long as you have enough reading and accumulation of literature, you can add a lot of words.

The explanation of noun concepts included in the theoretical basis can be more detailed, and the theoretical part can discuss the development of theory and the relationship between theory and paper in detail.

If there is a big difference in the number of words, you can consider an outline or a table of contents to see if you can add some content to the structure. Generally speaking, there is no problem to improve at the level.
