very far away; the heavenly shores
Literary four-character compound (yojijukugo) meaning an extremely distant place, often with a poetic or classical feel. Used in elevated or written contexts.
He set off for a land far, far away.
One's thoughts race to the distant heavenly shores.
遠方 is a common, neutral word for 'distant place', while 天涯万里 is a literary, poetic expression emphasizing extreme remoteness.
天涯 alone means 'the ends of the earth' or 'a remote place', but 天涯万里 intensifies the distance with the addition of 万里 (ten thousand miles).
A yojijukugo combining 天涯 (the edge of the sky, a distant place) and 万里 (ten thousand miles, a great distance). The exact historical origin is uncertain, but it follows classical Chinese poetic patterns for expressing vast distance.
