曲终人散也需要勇气
[qŭ zhōng rén sàn yĕ xū yào yŏng qì]
The literal meaning is that when a tune comes to an end and everyone disperses, courage is also needed. A beautiful music symbolizes happiness times. When a joy finishes and you must face solitude and silence, it requires courage. This nickname expresses nostalgia but acknowledges necessity to bid farewell.
