Analysis:
From Wang Zhihuan's In the Heron Villa, the stork house is located in Yongji County. It is three stories high, with Zhongtiao Mountain in front and the Yellow River at the bottom.
Described the scenery that the author climbed to the second floor and looked west. In the evening, the sun is blocked by the "ridge" of Zhongtiao Mountain and slowly sinks. When the author couldn't see the sinking sunset, he climbed to the third floor, so he wrote, "But you can broaden your horizons by going up a flight of stairs for 300 miles."
