Tips
history
From 《史记·游侠列传》, describing the knight-errant Guo Jie: '解为人短小精悍' — 'Guo Jie was short in build but sharp and tough.' The original applies to people; the 'concise writing' sense came later by analogy.
usage
For people, positive — small build + impressive ability. For writing, positive — brief but powerful. Never use it to mean merely 'short.'
