+## About me
 
-_You turned on GitHub Pages! :tada:_
+I am now a postgraduate student majoring in **computer science** at South China University of Technology.
+My research interests include **object detection, 3D object manipulation**. Currently I do not have any publication, but I shall have one or two in the next years.
 
-We'll work in a branch, `my-pages`, that I created for you to get this site looking great. :sparkle:
 
-Jekyll uses a file titled `_config.yml` to store settings for your site, your theme, and reusable content like your site title and GitHub handle. You can check out the `_config.yml` file on the **Code** tab of your repository.
 
-We need to use a blog-ready theme. For this activity, we will use a theme named "minima".
 
-### :keyboard: Activity: Configure your site
-
-1. Browse to the `_config.yml` file in the `my-pages` branch.
-1. In the upper right corner, open the file editor.
-1. Add a `theme:` set to **minima** so it shows in the `_config.yml` file as below:
-   ```yml
-   theme: minima
-   ```
-1. (optional) You can modify the other configuration variables such as `title:`, `author:`, and `description:` to further customize your site.
-1. Commit your changes.
-1. (optional) Create a pull request to view all the changes you'll make throughout this course. Click the **Pull Requests** tab, click **New pull request**, set `base: main` and `compare:my-pages`.
-1. Wait about 20 seconds then refresh this page (the one you're following instructions from). [GitHub Actions](https://docs.github.com/en/actions) will automatically update to the next step.
