苏欢笙绝
[sū huān shēng jué]
The first two characters, 'Su Huan,' denote 'joyful revival' and the latter two, 'Shengjue,' relate to a type of ancient Chinese musical instrument (reed pipe), often featured in grand farewell music. Combined it may express the bittersweet feeling after a joyful moment ends. Alternatively, a celebration of happiness followed by inevitable parting.
