青春 (qīngchūn) refers to the period of youth or the quality of being youthful, often with a positive, energetic connotation. It differs from 少年 (shàonián), which means a young person (roughly 10–15), and 青年 (qīngnián), which is the broader life stage of young adulthood (roughly 15–30). 青春 is more abstract, emphasizing the spirit or time of youth rather than a person's age range.
