**Which option to choose depends on your specific needs:**

* **Use Option 3** if you have a content that is quite broad.

**Important Considerations When Setting it in WordPress:**

* **Keep it short:** WordPress tag descriptions are usually displayed alongside the tag name, so brevity is good.
* **Keyword-rich:** Include relevant keywords without being overly verbose. “手機” (mobile phone) and “上網” (internet) are already there, but consider if there are related terms worth mentioning (e.g., “Wi-Fi”, “流量” (data usage)).
* **Consider your audience:** Tailor the language to the level of tech understanding of your target readers.
* **Always review the Chinese translation.** It’s best if you or someone fluent in Traditional Chinese reviews your content.

Remember to add the description in WordPress when you create or edit the tag! You’ll usually find a description field during the tag creation process.
