First of all, don't read papers and materials for a day or two, go out and relax your brain.

Secondly, the topic of the paper has been determined. In HowNet and Wan Fang data, you can search not only the keywords of this topic, but also others. For example, if you write cross-cultural translation, it is not necessarily only cross-cultural translation that can try to search translation history.

Furthermore, the undergraduate thesis should not be particularly difficult. If there are no other special circumstances, it is difficult to write or there are no relevant papers or materials, change the topic. Now I can't pass any scientific research papers.

Finally, I hope the LZ paper goes smoothly.
