Translation:The city moves away from the valley onto the mountain.
Is it about moving the city center, moving certain function of the city, not buildings? Whole city usually does not move.
I have no problem with non realistic sentences, but like to know when there is some realistic meaning included. Thanks for your answer!
Sometimes it does happen, after natural disasters, volcano, flood, or man-made reasons, like building a dam in a beautiful valley. Hopefully it is a very rare event.
