Here are a few options for the description of the “開燈 (Kāi dēng – Turn on the lights)” WordPress post_tag, catering to different levels of detail and SEO considerations:

**Option 1: Concise & Direct (Good for quick tagging):**

* **Description:** 開燈，方便、照明。 (Kāi dēng, fāngbiàn, zhào míng – Turn on the lights, convenient, illumination.) – (Provides a brief explanation of the action and its benefits.)

**Option 2: Slightly More Informative (Good for general use):**

* **Description:** 關於「開燈」的文章，包括室內外燈光的使用與維護，以及相關情境與主題。 (Guānyú “kāi dēng” de wénzhāng, bāokuò shì nèi wài dēngguāng de shǐyòng yǔ wéihù, yǐjí xiāngguān qíngjìng yǔ zhǔtí. – Articles about “Turn on the lights,” including the use and maintenance of indoor and outdoor lighting, as well as related scenarios and themes.) -(More detail about the kind of content it covers.)

**Option 3: SEO-Focused & Keyword-Rich (If you want to optimize for search, may be best for a standalone tag page):**

* **Description:** 開燈，照明，燈光，室內照明，戶外照明，節能，燈泡，LED，照明設計，家居照明。 (Kāi dēng, zhào míng, dēngguāng, shì nèi zhào míng, hù wài zhào míng, jié néng, dēngpào, LED, zhào míng shèjì, jiā jū zhào míng. – Turning on the lights, lllumination, lighting, indoor lighting, outdoor lighting, energy saving, light bulbs, LED, lighting design, home lighting.) – (Includes relevant keywords that people might search for related to lighting.)

**Key Considerations when choosing a description:**

* **Relevance:** Ensure the description accurately reflects the *type* of content tagged with “開燈.”
* **Target Audience:** Tailor the language to your audience’s familiarity with the subject and technical jargon.
* **Length:** Keep it relatively concise. WordPress tag descriptions are typically displayed on the tag archive page and should be easy to read.
* **SEO (If applicable):** If you want this tag to rank well in search engines, consider including relevant keywords (Option 3). If you have a lot of content and want to create a more full-featured SEO-focused tag page, this is important; if you only very rarely write about light, maybe skip the focused SEO.

I recommend starting with Option 2 or 4 for their balance of informativeness and approachability, and then adapting it based on your specific needs. Good luck!
