Here are a few options for a description of the WordPress post tag “外島” (Wài dǎo, meaning “Outlying Islands” in Traditional Chinese), ranging from concise to slightly more detailed:

**Option 1: Concise**

* **Description:** 指台灣及其他地區的離岸島嶼。 (Zhǐ Táiwān jí qítā dìqū de lí’àn dǎoyǔ. – Refers to offshore islands of Taiwan and other regions.)

**Option 2: Slightly More Detailed**

* **Description:** 涵蓋台灣及其它地區，遠離本島的島嶼，包括澎湖、金門、馬祖等，也可能包含其他國家的島嶼。 (Hāngài Táiwān jí qítā dìqū, yuǎnlí běndǎo de dǎoyǔ, bāokuò Pénghú, Jīnmén, Mǎzǔ děng, yě kěnéng bāohán qítā guójiā de dǎoyǔ. – Covers islands far from the main island of Taiwan and other regions, including Penghu, Kinmen, Matsu, etc., and may also include islands of other countries.)

**Option 3: Emphasis on Travel/Tourism**

* **Description:** 探索台灣及其他地區的離島風光，包含澎湖、金門、馬祖等迷人景點，享受獨特的旅行體驗。 (Tànsuǒ Táiwān jí qítā dìqū de lídǎo fēngguāng, bāohán Pénghú, Jīnmén, Mǎzǔ děng mírén jǐngdiǎn, xiǎngshǒu dútè de lǚxíng tǐyàn. – Explore the scenery of offshore islands in Taiwan and other regions, including charming attractions like Penghu, Kinmen, and Matsu, and enjoy a unique travel experience.)

**Option 4: Technical and Inclusive**

* **Description:** 本分類標籤包含所有關於外島的內容，泛指位於主要島嶼邊緣或遠離的其他島嶼。 包含台灣、香港、中國或其他地區的離岸島嶼。 (Běn fēnlèi biāoqiān bāohán suǒyǒu guānyú wàidǎo de nèiróng, fànzhǐ wèi yú zhǔyào dǎoyǔ biānyuán huò yuǎnlí de qítā dǎoyǔ. Bāohán Táiwān, Xiānggǎng, Zhōngguó huò qítā dìqū de lí’àn dǎoyǔ. – This tag includes all content related to offshore islands, generally referring to islands located on the periphery or far from the main islands. Includes offshore islands of Taiwan, Hong Kong, China, or other regions.)

**Which option to choose depends on the purpose of the blog and the overall tone.** Consider:

* **The overall focus:** Are you primarily a travel blog, or do you cover other topics like politics or geography?
* **Your target audience:** What level of detail would they appreciate?
* **Search Engine Optimization (SEO):** You might consider keywords related to the islands you will write about (e.g. 澎湖 (Penghu), 金門 (Kinmen) ) if you want to emphasize the specific islands featured within the content.
* **Number of words you can use.**

I recommend starting with **Option 1** or **Option 2** unless you have specific topics in mind like travel, then go with **Option 3**. Remember you can always edit the description later. Good luck!
