In the Han Dynasty, the stone carving "Treading the Xiongnu" in front of Hou Huo's sick tomb (see Figure 7-20) constitutes the beauty of the whole. In the early years of the Western Han Dynasty, Huns in the north often invaded the border, posing a great threat to the Central Plains. In 123 BC, when General Wei Qing stopped the Huns in Dingxiang, Huo Qubing (BC 140- BC17), who was only 18 years old, made great achievements and was named the champion. In 65438 BC+02 BC1year, Huo Qubing lived in the city. In 65438 BC+065438 BC+09 BC, Huo Qubing led the Han army to attack, reaching more than 2,000 miles north of Daizhou and reaching Xushan (now east of Ulaanbaatar), which made the Huns lose confidence and made Huo Qubing Weizhen a frontier. Huo Qubing died in 1 17 BC at the age of 24. Emperor Wu of the Han Dynasty was very sad and specially ordered Huo Qubing's tomb to be built next to his own tomb under construction. To commemorate Huo Qubing's fierce battle under Qilian Mountain, the mausoleum was built in the shape of Qilian Mountain. Vegetation is widely planted in the cemetery, and there are many animals carved with granite squatting on the hillside, such as cattle, horses, wild boar, tigers and so on. There is a huge stone carving in front of Huo Qubing's tomb, which is 1.9 meters high and looks like a tombstone. This is the famous Western Han Dynasty stone carving "Horse Treading on Xiongnu".
