Yi Qi Rangxian introduced: During the Shang Dynasty more than 3,000 years ago, Luanzhou was the seat of the Guzhu Kingdom. Boyi and Shuqi were the princes of Guzhu Kingdom. The first king passed away and the two princes respectfully abdicated. Later, it was believed that the Zhou Dynasty usurped the throne against the Shang Dynasty, ate Zhou millet in shame, and died of starvation on Shouyang Mountain, becoming a model of Chinese loyalty.
