Sacred Soil Mountain

　　　　Located at the northeastern tip of Shagou Town, the main peak stands at an elevation of 374.3 meters, making it the highest mountain in the entire region. To the east of Sacred Soil Mountain is Yangbizi Mountain, with an elevation of 362 meters, ranking as the second highest mountain in the area. The northern slope of Sacred Soil Mountain is relatively gentle, while the southern cliffs are steep, dropping tens of meters to form the unique "half-crag" terrain of southern Shandong, where the top of the crag is flat. In the 1980s, a 6.5-kilometer winding mountain road was built to reach the summit due to the construction of a television transmission tower on the mountain. This peak stands opposite the nearby “Huanglouzi Mountain,” with the mountain pass between them known as “Huangkoukou,” which was once a vital section of the ancient post road — a true “one man can hold the pass against ten thousand” strategic site. To the east of Sacred Soil Mountain lies the Eastern Valley, later mistakenly referred to as “Cheyu.” The cliffs on both sides of Cheyu Valley are steep and majestic, making it one of the rare and spectacular mountain landscapes in the area. Beside the ruins of the “Warning Temple” within the valley lies a spring called “Sacred Soil Spring,” also known as “Warning Spring.” It has a strong flow of water, serving as the drinking supply for the entire Shiliu Mountain Village, and never dries up throughout the year.
