**Choosing the best option:**

* **Length:** Choose the length based on where the description will be displayed. A short option is often best for a tag cloud or a list. A longer one is good for tag archive pages.
* **Focus:** Consider what the content under the “肢體語言” tag will primarily address. If it’s more about practical tips, option 3 might be a great fit. If it dives into the science and interpretation, option 2 would be more appropriate.
* **Audience:** Think about your target audience. If they’re likely to know a lot about the topic, you could be more technical. If they’re beginners, the language should be simpler.
* **Keywords:** Remember to include relevant keywords like 手勢 (gestures), 表情 (facial expressions), 姿勢 (postures), 溝通 (communication), 人際關係 (interpersonal relationships).

You can always adapt and mix the components to fit your specific needs. I recommend using the Traditional Chinese characters you want to use in your actual WordPress setup to ensure they render correctly.
