推广 means 'to promote widely' or 'to popularize'—it describes the active effort to make something (a product, idea, method, or practice) known and accepted by a broad audience. The character 推 (tuī) means 'to push' or 'to advance', suggesting initiative and forward motion; 广 (guǎng) means 'broad' or 'extensive', emphasizing scale and reach. Together, they convey the sense of pushing something outward into wider circulation or adoption.

This verb is commonly used in business, education, public policy, and technology contexts—for example, promoting new teaching methods in schools, launching marketing campaigns, or encouraging sustainable farming practices. It implies intentionality and effort, not just passive exposure. While often associated with formal or institutional efforts, it can also describe grassroots initiatives. Note that 推广 is almost always transitive—it requires a direct object (e.g., 推广技术, 推广经验), and rarely stands alone.
