1. Landscape diversity: There are a large number of pine trees and various birds in Songmingyan Park, and a grand flower show is held here every April. At the same time, there are many spectacular natural landscapes in the park, such as peaks, canyons, waterfalls and lakes. In contrast, the landform of Yeliguan is relatively simple, mainly composed of canyons and mountains.

2. Cultural background: Songmingyan is a famous historical and cultural scenic spot in Gansu Province, with rich historical relics and cultural connotations. For example, there is an ancient Tibetan Buddhist temple in Songmingyan-nanzenji, where many precious Buddhist cultural heritages are preserved. In Yeliguan, although there are some historical and cultural relics, compared with Songmingyan, the quantity and quality are inferior.
