Final line of Li Bai's (
李白) Tang poem
《行路难·其一》 (Hardships of the Road, I). After cataloguing frustrations and dead-ends, Li Bai ends on a defiant upswing:
长风破浪会有时,直挂云帆济沧海 - 'A time of riding wind and breaking waves will surely come; I will hoist my cloud-sail straight and cross the vast ocean.' A classic image of reclaimed confidence after setback.
