Walking on the coast plank road, watching the sun shining on the sea, I finally knew that those who could not understand the learned idioms had a real feeling for the first time. There is no-one charging oranges on the roadside, just a card with a price, and tourists pay consciously. Like the blue sea water of Jeju Island for the first time brought the amazing feeling and shock, like the feeling of walking on the beach with the sea breeze.
