**Key Considerations when choosing the description:**

* **Target Audience:** Who are you writing for? (General public, parents, medical professionals, etc.)
* **Content Focus:** What kind of content will be tagged with “身體發育”? (General health, specific age groups, related to a condition, etc.)
* **Keywords:** Consider adding relevant keywords to improve SEO (e.g., 生長, 健康, 兒童, 青少年, 營養, etc. – growth, health, children, adolescents, nutrition) within the description if it suits the content. You indirectly include them by using them in the description.
* **Length:** Keep it concise, but informative. WordPress handles a certain length of description better than very long ones.

Choose the description that best represents the content and your target audience. It’s also fine to choose a more general description and then refine it later as you add more content to the tag if the focus changes.
