天长地久演不完的戏唱不完的歌情以何堪
[tiān zhăng dì jiŭ yăn bù wán de xì chàng bù wán de gē qíng yĭ hé kān]
'Endless plays and endless songs in eternal time' reflects the enduring nature of relationships, implying that there is always more drama and emotion that cannot be easily expressed or finished. The phrase conveys complex feelings about love and time.
