**Things to Consider When Choosing:**

* **Your Blog’s Focus:** What kind of content do you *actually* plan to publish under this tag? The description should match.
* **Target Audience:** Who are you writing for? Is it a medical audience? A general audience? Adjust the level of detail and formality accordingly.
* **Keywords:** Including relevant keywords (like “搔癢”, “皮膚過敏”, “濕疹” – Itch, skin allergy, eczema) in the description can help with search engine optimization (SEO), and improve search internally for readers looking for help..
* **Character Count:** WordPress sometimes has character limits for descriptions, especially if you’re using a plugin. Keep your description concise.
* **Use the Chinese of your targeted audience:** If you blog is in Mandarin Chinese, avoid Cantonese, and vice versa, or if your blog target readers from mainland China or Taiwan.

To implement, go to your WordPress post tag settings (usually within the “Tags” section under “Posts”) when you create a Tag and insert the description in the respective box and save it.
Good luck!
