Here are a few options for the WordPress post_tag description “培養慈悲” (Cultivating Compassion) in Traditional Chinese, along with explanations to help you choose the most suitable:

**Option 1 (Concise and General):**

* **Explanation:** This is a short, direct, and easily understood description. It focuses on the core benefits of cultivating compassion.

**Option 2 (Emphasizing the Process):**

**Option 3 (Focusing on the Outcome):**

**Option 5 (Simplified for broader audience):**

> **學會關懷，體諒他人。** (Learn to care and be considerate of others.)

* **Explanation:** Very simple language, suitable for a wider audience.

**Which Option to Choose:**

* **Consider your target audience:** Are you writing for a general audience, those familiar with Buddhist concepts, or a specific group?
* **The tone of your blog:** Does your blog lean towards being casual, academic, or spiritual?
* **The content of your related posts:** What information will you be providing in the actual blog posts?
* **Frequency of your post_tags usage:** How often will you be using this particular key word/tag.

I recommend choosing the one that best aligns with your blog’s overall style and the specific content related to the “培養慈悲” tag. For most WordPress sites in my general opinion, **Option 2 or Option 3** are great. The most important thing is it should be very relevant, descriptive, and of course in Traditional Chinese!
