How it's used

When applied to information or experience, it emphasizes that the source is direct and authentic rather than hearsay. It is the direct opposite of 二手, which refers to second-hand or used items.

Common mistake

Avoid using this to mean a single hand or a single action, as it is strictly a modifier for status or origin. Learners often confuse it with the literal meaning of one hand, but in a commercial or informational context, it always refers to the primary source.
