The Tianchi Lake Group is located in Luya Mountain Scenic Area. It is centered on Luya Mountain Tianchi (also known as Mayinghai Lake) and consists of 15 sapphire-like lakes such as Yuanchi Lake and Pipahai Lake. It is a rare alpine lake group in northern China. The largest lake in the Tianchi Lake Group is called Tianchi Lake. Local people call it "Mayinghai Lake" or "Mother Sea". It is the largest lake in the Tianchi Lake Group. Its average water depth is 8 meters, the area is 0.607 square kilometers, and the water storage capacity reaches 8 million cubic meters. From the first year of the Zhenguan reign to the Yifeng period, the Tang Dynasty established 8 wards and 64 prisons in the northwest to raise official horses. Among them, the three major pastures of Tianchi, Yuanchi and Loufan were set up in the Guancenshan area alone. The three pastures trained 700,000 military horses. At that time, "there were tens of thousands of horses, divided into groups according to their colors, and they looked like clouds at a glance", leaving behind the stories of "Loufan produces fine horses" and "Loufan's pastoral administration is the best in the world". At that time, the Loufan horses produced in the Tianchi area and the fine horses produced in the Western Regions were as famous as ever in the world, and made immortal contributions to the prosperity and growth of the Tang Dynasty.
