What places that look high are actually low?

The natural landscape of Jeju Island is "magnificent". For example, Tiandiyuan Waterfall, known as the first waterfall in Korea, is only 22 meters high. You can kill a small waterfall in this country in a few minutes. The legendary Halla Mountain is even more difficult to see the lineup. The following is the true experience of a good friend: I went to Jeju Island a few years ago and said I was going to Halla Mountain. In fact, the driver drove the bus around the mountain, and then the tour guide was in the car, holding the following publicity photo and telling us, "Look, Hannah Mountain in spring is like this." But what we actually see is a bare stone and a wasteland, okay?
