Grandpa, who had a very precise eye for the ground

(1)My grandfather had a very good eye for land and bought quite a lot of land in his life
(2)How accurate my eyes were: All the land that my grandfather bought was designated as Naejangsan National Park and tied to a green belt that would not be released for life
(3)The only land in the world that bought the most is the only land in the world
(4)A colony of oyster trees was found and even designated as a natural monument
(5)It’s specialized in looking at pretty land
