昔我往矣杨柳依依
[xī wŏ wăng yĭ yáng liŭ yī yī]
The phrase ‘In the Past There Were Willows Gently Fluttering When I Left’ is from an ancient Chinese poem about the poignant nostalgia one feels when recalling the beauty and melancholy of past experiences, specifically referencing a time of departure under gentle willow trees.
