想开心就要舍得伤心
[xiăng kāi xīn jiù yào shè dé shāng xīn]
Translated, it roughly means 'to want happiness, you have to dare to be sad.' The name embodies a philosophical notion: to fully experience joy, one must be brave enough to confront the sadness. One needs the courage and willingness to experience low times if they hope to achieve higher pleasures.
