Here are a few options for a description for the WordPress post_tag “非正式場合” (Informal Occasions) in Traditional Chinese, ranging in style and focus:

**Option 1 (Concise & Broad):**

> 涵蓋各種輕鬆、隨性、不拘束的活動和場合。

> *Translation: Covers various relaxed, casual, and unfettered activities and occasions.*

* **Why it works:** Simple, direct, and easily understood. Good for a general overview.

**Option 2 (More Descriptive):**

> 這個標籤適用於描述那些無需正式著裝、禮儀較少、適合與朋友、家人或同事輕鬆交流的場合，例如聚餐、閒聊、戶外活動等。

> *Translation: This tag applies to descriptions of occasions that require no formal dress, have fewer protocols, and are suitable for casual interactions with friends, family, or colleagues, such as gatherings, chats, outdoor activities, etc.*

* **Why it works:** Provides more context and examples, making it clearer what kind of content this tag is relevant to.

**Option 3 (Emphasis on Style/Tone):**

> 分享關於輕鬆、隨性、氛圍自在的場合的相關文章，包括服裝、活動安排、社交禮儀等等。

> *Translation: Share articles about relaxed, casual, and comfortable occasions, including clothing, activity arrangements, social etiquette, and so on.*

* **Why it works:** Focuses on the content that users might expect to find, emphasizing the style and perspective of the articles.

**Option 4 (Emphasizing vs. Formal):**

> 用於標記與”正式場合”相對的、更為輕鬆自如的社交、聚會、和活動內容。

> *Translation: Used to tag content related to social events, gatherings and activities that are in contrast to “formal occasions” and being more easy- going.*

* **Why it works:** Clear if the site also has a “Formal Occasion” tag, emphasizing the contrast between the two.

**How to choose:**

* **Consider your target audience:** Who are you writing for? What are they likely to understand?
* **The theme of your blog/website:** What is the overall tone of your content?
* **The scope of your content:** What kind of articles do you plan to post with this tag?

I recommend you choose the option that best fits your specific needs. Remember to translate the description using the WordPress interface when you create the tag, if you haven’t already. Choose the one that offers the right degree of clarity for your readers and the content you create. Good luck!
