Here are a few options for a description for the WordPress tag “空頭” (meaning “empty head” or “airhead” in Traditional Chinese), ranging from concise to slightly more elaborate, depending on your needs:

**Option 1 (Concise):**

> 泛指思想空洞、缺乏知識或思考的人。 (Fàn zhǐ sīxiǎng kōngdòng, quēfá zhīshi huò sīkǎo de rén.) – Refers to people with empty minds, lacking knowledge or critical thinking.

**Option 2 (Slightly More Descriptive):**

> 標籤用於標記涉及思想遲鈍、不切實際或缺乏深度思考的人物、事件和內容。 (Biāoqiān yòng yú biāojì shèjí sīxiǎng chídùn, bù qiè shíjì huò quēfá shēndù sīkǎo de rénwù, shìjiàn hé nèiróng.) – Tag used to categorize people, events, and content relating to slow thinking, impracticality, or lack of deep thought.

**Option 3 (Adding Nuance):**

> 用於區分指涉愚笨、思想空洞，或是對事物缺乏深刻理解的內容。也可用於帶有輕微玩笑色彩，形容天真、單純或偶爾犯蠢的人。 (Yòng yú qūfēn zhǐ shè yúbèn, sīxiǎng kōngdòng, huò shì duì shìwù quēfá shēnkè lǐjiě de nèiróng. Yě kě yòng yú dài yǒu qīngwēi wánxiào sècǎi, xíngróng tiānzhēn, dānchún huò ǒu’ěr fàn chǔn de rén.) – Used to categorize content referring to stupidity, empty-headedness, or a lack of deep understanding of things. Can also be used playfully to describe naivete, simplicity, or occasional moments of silliness.

**Option 4 (If the context is specifically about online content):**

> 專為標記網路文章、討論、影片等，與「空頭」相關的內容而設。可能涉及愚蠢言論、缺乏深度思考、或是單純有趣的愚笨片段。(Zhuān wèi biāojì wǎng lù wénzhāng, tǎolun, yǐngpiàn děng, yǔ “kōngtóu” xiāngguān de nèiróng ér shè. Kěnéng shèjí yúchǔn yánlùn, quēfá shēndù sīkǎo, huò shì dānchún yǒuqù de yúbèn piànduàn.) – Specifically for tagging online articles, discussions, videos, etc., related to “airheads.” This might involve foolish comments, lack of deep thinking, or simply amusing snippets of silliness.

**Choosing the Right Option:**

Consider the overall tone and content of your blog. If it’s more serious, Option 1 or 2 is suitable. If it’s more relaxed or you intend to use the tag playfully, Option 3 is a good fit. If your blog focuses on online content, Option 4 would be the most appropriate. Remember to translate “WordPress” with the correct phrase for your target audience, e.g., “WordPress 標籤”.
