Most often a transliteration of the Korean given name 준하 (Junha) — popularized in Chinese-speaking subtitles for the long-running Korean variety show 《
无限挑战》 (Infinite Challenge), where
郑俊夏 (Jeong Jun-ha) was a main cast member. As a Chinese given name
俊 ('handsome / talented') +
夏 ('summer') is uncommon but legitimate.
