爱情是一场赌局
[ài qíng shì yī chăng dŭ jú]
The nickname 'Ai Qing Shi Yi Chang Du Ju' is translated into 'Love Is A Gamble', signifying that love bears unpredictable risks just like in gambling games; sometimes it brings unexpected fortune, but most times, one could face disappointment or even lose everything. The phrase implies a sense of adventure and risk, and possibly a reflection of the unpredictable nature of love and emotions.
