"When Will You Return?" (Chinese: 何日君再來; pinyin: Hé Rì Jūn Zài Lái) is a Chinese song first sung by Zhou Xuan in 1937, but also well known as a song by Teresa Teng. It has also been variously translated as "When Will the Gentleman Come Back Again?" or "When Will You Come Back Again?" The lyrics were written by Huang Jiamo (黃嘉謨) set to a tune composed by Liu Xue'an.
