我用三世烟火换你一世迷离
[wŏ yòng sān shì yān huŏ huàn nĭ yī shì mí lí]
Literally: 'I trade three lifetimes of fireworks (or worldly splendor) for one lifetime of enchantment from you.' Symbolically, it represents sacrificing everything for love, exchanging one's whole existence for a chance at capturing someone's heart.
