Here’s a description for a WordPress post tag “走失” in Traditional Chinese, along with some considerations:

**Option 1: Concise and Direct (Good for General Use)**

* **Title:** 走失
* **Description:** 描述與走失相關的文章，包括人物、寵物或物品的遺失及相關資訊。 (Describes articles related to being lost, including missing people, pets, or items and related information.)

**Option 2: More Contextual (For a Blog Focused on Community/Safety)**

* **Title:** 走失
* **Description:** 分享走失相關的資訊，例如協尋啟事、預防走失的方法、以及如何協助走失者。 (Sharing information related to being lost, such as missing person notices, methods of preventing loss, and how to help those who are lost.)

**Option 3: Emphasizing the Emotional Aspect (For topics on human/animal welfare)**

* **Title:** 走失
* **Description:** 探讨走失背后故事及其引发的担忧。此标签适用于讲述关于走失事件的报道、寻求帮助或提供协助的帖子。 (Exploring the stories behind being lost and the anxieties it causes. This tag is suitable for articles about reports of missing people, for seeking help, or providing assistance.)

**Explanation of Considerations:**

* **Target Audience:** Consider who you are writing for. If it’s a general blog, the more basic option might be better. If you are involved in the community, the second option might fit better.
* **Content Focus:** The description should accurately reflect the types of content your blog will tag with “走失.” If you’re just sharing news of lost pets, the first option would be sufficient. If you provide advice or resources, option 2 might be more apt.
* **SEO (Optional):** While descriptions primarily serve the user, a well-crafted description also helps with search engine optimization (SEO). You might include related keywords (e.g., “協尋”, “寵物走失”, “兒童走失”) if relevant to your blog’s subject matter.

**How to use in WordPress:**

1. **Go to Posts > Tags (in the WordPress admin).**
2. **Add New Tag:** Fill in the following:
* **Name:** 走失 (This is the title).
* **Slug:** WordPress will create a slug automatically, or you can customize it (e.g., zou-shi, but using the Chinese characters is usually best).
* **Description:** Paste the description of your choice.
3. **Click “Add New Tag.”**

When writing a new post, you can then select the “走失” tag to categorize content.
