**To choose the best option:**

* **Consider your audience:** Who are you writing for? (Beginners? Experts?)
* **Think about the overall tone of your blog/website.**
* **Decide how much information you want to convey.**

I recommend Option 2 or 3 for a good balance of information and readability. Remember to translate the descriptions to Traditional Chinese using a reliable translation tool like Google Translate or a dedicated Chinese translation service or translator. Good luck!
