众里寻你千百度你却灯火阑珊处
[zhòng lĭ xún nĭ qiān băi dù nĭ què dēng huŏ lán shān chŭ]
This means 'I have searched for you a thousand times among crowds, only to find you at last where the lantern lights dimly'. It describes the experience of finally finding something or someone important after countless tries; inspired by ancient poems which talk about unceasing searches and ultimate fulfillment.
