Introduction to the Millennium Earth Arrow Group: The "Millennium Earth Arrow Group" is a loess cliff that is as neat as an axe, as jagged as a Buddha's finger, and as isolated as a pillar holding up the sky. Looking at this loess arrow group that looks like a forest of arrows and stands thousands of feet high on the wall, It not only makes people feel the miraculous creation of nature, but also reminds people to be alert to the control of water and soil erosion and realize the historical importance of soil and water conservation work that "serves the present and will benefit the future".
