你若情长她命必短
[nĭ ruò qíng zhăng tā mìng bì duăn]
'Ni Ruo Qing Chang Ta Ming Bi Duan' ('If You Love Deeply, Her Life Must Be Short') implies a fatalistic view on intense relationships suggesting that too deep feelings in love may bring sorrow or bad results. This kind of saying comes sometimes from traditional literature where strong emotional stories often end tragically.
