can anyone write down 3-4 reasons why people love the great wall

People love the Great Wall because it is a symbol of the great Chinese people;people consider it as a place of interest because they can get a very beautiful view of nature from here;people describe it as a very difficult place to reach,as the famouse saying goes"He who never reaches the Great Wall is not a real man.";when people climb up onto the Great Wall,people can't help think of the past of China and value the present life.
