Here are a few options for a WordPress post_tag description for “籠子” (Cage) in Traditional Chinese, catering to different contexts:

**Option 1: General & Concise**

* **Description:** 一種用來限制或保護動物、鳥類、甚至是物品的容器。 (A type of container used to confine or protect animals, birds, or even objects.)

**Option 2: More Descriptive & Evocative**

* **Description:** 用木材、金屬或其他材料製成的籠子，具有各種形態和用途，從關押動物的牢籠，到用於運輸或裝飾用途的精美籠子，都反映了人类历史和文化。 (Cages made from wood, metal, or other materials, having various forms and purposes, from prisons for animals to delicate cages for transportation or decoration, reflecting human history and culture.)

**Option 3: Focused on the WordPress Post’s Content (Adapt to your post!):**

* **Description:** 在關於籠子之主題、案例研究、圖片或產品比較的文章中使用。 ([Use for posts] about the topic of cages, case studies, images, or product comparisons.) **(Remember to tailor this part to the specific content of your posts.)**

**Option 4: Addressing both literal and metaphorical usage (More nuanced):**

* **Description:** 籠子，可以是實質的容器，用於關押或保護。也可以是比喻，代表限制、束縛，或自我禁錮的心理狀態。 包含籠子相關的主題與內容，包括實體的籠子，以及籠子所代表的象徵意義。 (Cage: It can be a literal container used for confinement or protection. It can also be a metaphor representing limitations, constraints, or a self-imposed psychological state. Includes all related topics and content related to cages, including the physical ones and the symbolic meanings that they represent.)

**Tips for Choosing:**

* **Consider your audience:** Are they familiar with Chinese, or might they be using an online translator.
* **Match the tone of your blog:** Are you formal or informal?
* **Think about your main content:** The description should help people find relevant posts.

Once you choose, simply copy and paste the descriptions into the appropriate WordPress post_tag description field when you are adding or editing your tags. Remember to select the description field, which may be hidden by default and needs to be toggled open. (Usually, to find the “description” field, you need to select it via “show options” at the very top of your page for the tags.)
