研究方向
This issue involves replacing a PNG image in the README.md file with a GIF demonstrating the first exercise. The exact location is the README file in the root of the repository. As the issue is from 2020 with no recent activity, a contributor should ensure they are working on the current version. No additional context or blockers are present.
