**How to choose the best description:**

* **Consider your target audience:** Who are you writing for? Are they experienced travelers or beginners?
* **Think about the content the tag will categorize:** What kind of posts will you be tagging with this? Photos? Tips? Reviews?
* **Keep it concise:** While descriptive, try to keep the description relatively short for readability.
* **Use keywords:** If you’re aiming for SEO, include relevant keywords like “海洋 (ocean)”, “假期 (vacation)”, “海灘 (beach)”, “潛水 (diving)” etc. (It’s already quite good with current title.)

You can use these options, or customize them to better fit your specific needs. When adding the description in WordPress, you’d typically input it in the “Description” or “Tag description” field when editing the tag.
