**How to Use This in WordPress:**

1. **Log in to your WordPress dashboard.**
2. **Go to “Posts” > “Tags”.**
3. **Click on the “well-being” tag (or “健康” if you have already created it).**
4. **In the “Description” field, paste your chosen description from above.**
5. **Click “Update”.**

**Key Considerations:**

* **Target Audience:** Consider your target audience’s level of Chinese proficiency when choosing the description.
* **Content of Your Site:** Make sure the description aligns with the overall tone and content of your blog.
* **Keywords:** While not strictly a keyword, it is a good practice to have relevant terms that would make sure your tag is searchable, the description may aid in that.

Adapt the description if needed to fit your specific blog and brand. Good luck!
