《離人愁》是劉增瞳演唱的歌曲，由孫莞作詞兼作曲，於2018年成為最受歡迎的歌曲之一。本人把這首改編成鋼琴三重奏版本，以忠實呈現原曲的風味。
本人曲譜的特色，在於小提琴和大提琴扮演二重唱的角色，用二重唱的方式來演奏此歌曲；而鋼琴只扮演陪襯的伴奏角色，尤其到最後的樂曲片段，小提琴和大提琴一起合奏主旋律的片段，更可襯托出二重唱的光影。喜歡一起演奏的演奏者，可以購買本人的曲譜來試試。
"Legacy" is a song sung by Liu Zengtong, written and composed by Sun Guan, and became one of the most popular songs in 2018. I adapted this piece into a piano trio version to faithfully present the flavor of the original song.
The characteristic of my music score is that the violin and cello play the duet role, and the song is played in the form of duet; while the piano only plays the accompaniment role of the accompaniment, especially to the final piece of music, the section of the main melody of the violin and cello together, even more Set off the light and shadow of the duet. Players who like to play together can buy their own music to try.
