What does Faye Wong's fleeting lyric "The palm suddenly grows tangled curve" mean?

"The palm of your hand suddenly grows a tangled curve" means that (my) marriage feelings have been cut and confused.

In physiognomy, a woman's right hand is innate "fate" and her left hand is acquired "luck". Handprints are constantly changing over the years, getting deeper and shallower with the increase of experience. Many people like to compete with each other when their fate is bad, expecting a sudden curve of liberation and a happy marriage.
