**Key Considerations when choosing a description:**

* **Content of your Posts:** The description should accurately reflect the content of the posts associated with this tag.
* **Keywords:** Include relevant keywords (like 換算 – conversion, 照顧 – care, 健康 – health) to help with search engine optimization (SEO).
* **Target Audience:** Consider who you’re writing for. A more casual description is fine for a general audience, while a more technical one might suit a more knowledgeable one.
* **Length:** WordPress allows for longer descriptions but shorter, concise descriptions are generally preferred. A good starting point is to keep it to one or two sentences.

I recommend selecting the option that best fits both the content of your posts and the overall tone of your website. If your posts cover a wide range of dog-age topics, options 2, 3, or 4 would be appropriate. If it’s mostly about age conversion, option 5 is excellent. Good luck!
