The Xixia Ancient City is located in the southern part of the Ejina Oasis, on the edge of the desert on the west bank of the Ejina River Valley, and is a mysterious ancient city. The ancient city of Xixia is located in the southern part of the Ejina Oasis, on the edge of the desert on the west bank of the Ejina River Valley. It hides a mysterious ancient city, which was the Yijina city that Marco Polo visited during his travels in China. The local people call it the Black City. The scale of the city is not small, much larger than the Zhenbei Fort in Ningxia, and the surrounding city walls still leave behind a 5.6 meter high remnant wall. Wandering within the city, one can vaguely discern traces of streets over 800 years ago, as well as remnants of houses. The neat eaves emerged from the quicksand, as if they had been buried recently. It is said that this Black City was built during the Western Xia Dynasty, and historical records record that as early as the Western Han Dynasty, Emperor Wu of Han sent troops to cultivate fields here and built the Great Wall to Juyanhai. There is a folk legend that is even more heartwarming. It is said that the Yuan army attacked the city, and a black general defended it for many years. Eventually, the water source was cut off by the Yuan army and the city was abandoned. Before retreating, he hid all the treasures in the city in a dry well. During the retreat, the black general died in battle, and the people and remaining soldiers were also killed. As a result, the treasure trove was never found. This legend has attracted countless treasure explorers in later generations, including Sven Herding of Sweden, Speyne of England, and Kozlov of Russia. Baojing was never found, but many cultural relics from the Western Xia and Yuan dynasties were taken away, which are more precious than gold, silver, and jewelry。There are two animation cameras in the scene, and the tree placement uses the plugin: MultiScatter WorkStation Version 1.2.0 twelveModel making software: 3ds Max 2014 Rendering software: vray3.60.03 for 3dmax2014
