Here are a few options for the WordPress post_tag description, along with explanations to help you choose the best fit:

**Option 1: Short and Sweet (Focus on the Problem)**

* **Description:** 孩子社交困難，如何幫助他們建立良好人際關係？
* **Translation:** Child social difficulties, how to help them build good relationships?
* **Why this works:** Direct, concise, and likely to attract users specifically searching for solutions to this problem. It uses a question format which can be more engaging.

**Option 2: Emphasis on Causes**

* **Description:** 探索孩子人緣不好的原因，包括性格、溝通技巧等。
* **Translation:** Exploring the reasons why a child doesn’t have good social skills, including personality and communication skills.
* **Why this works:** Focuses on the aspects that would lead one to be unpopular with peers. A search for causes/reasons is a common search term.

**Option 3: Focus on Solutions/Strategies**

* **Description:** 提供改善孩子人緣的技巧、方法，以及家長如何支持。
* **Translation:** Offers techniques/methods to improve a child’s social skills, and how parents should support them.
* **Why this works:** This is action-oriented and focuses on helping the reader. This might attract users actively seeking guidance.

**Option 4: Broad and Welcoming**

* **Description:** 關於孩子人際關係、社交技巧、以及人緣不好的相關討論。
* **Translation:** Related discussions on children’s interpersonal relationships, social skills, and not having friends.
* **Why this works:** Offers a broader scope, which might catch more general interest.

**How to choose the best option:**

1. **Target Audience:** Who are you trying to reach? Parents? Teachers? The description should resonate with their needs and concerns.
2. **Content Focus:** Does your post primarily discuss causes, offer solutions, or a combination? Choose a description that reflects the content of your post.
3. **Keyword Relevance:** Use terms like “人緣” (social skills, popularity), “孩子” (children), “社交” (social), and the keywords in your post.
4. **Length Considerations:** WordPress tag descriptions are generally best kept concise. The shorter the better, generally speaking.

**I recommend starting with Option 1 or 3, as they are the most actionable and likely to attract the right audience.** Adjust the description based on which best suits your specific blog post content.

Most importantly, make the description relevant to the specific content covered in your blog post. Don’t use fluffy terms or generalities if you can convey specific information that the audience is looking for via your description. Good luck!
