After the relationship between Wusunma and Ilima is clarified, let's go back to the history of horses with curiosity.
The history of horses is tens of millions of years earlier than that of humans. "Flying into the sky" and "riding a swallow" are both good horses deified in China's legend. The most magical bloody BMW that is not "traveling thousands of miles a day" belongs to it. It is said that the little red horse in Guo Jing in Legend of the Condor Heroes is the magical bloody BMW.
Blood horse is called Tianma and Bowl Horse in history. According to records, Zhang Qian was a good horse when he went to the Western Regions, and was especially cherished by Emperor Wu of the Han Dynasty. He named it "Tianma". Later, he won the Dawan Blood Horse, which was better than Wusun Horse. Emperor Wu of the Han Dynasty transferred the title of "Tianma" to Dawan Blood Horse. The former Wusunma was later renamed as "Xijima".
The ancestor of the blood horse is a wild horse growing in the remote desert Gobi. It is said that when it runs, sweat with red substance will flow out of its neck. Because its sweat is as red as blood, it is named "Blood Horse". In order to get the blood horse that he missed so much, Emperor Wu of the Han Dynasty once sent a strong man to bring a thousand kilograms of gold and a golden horse of the same size in exchange for a blood horse. After the failure, two large-scale expeditions to Dawan country. King Dawan sized up the situation and saw that he was no match for the Han Dynasty. He threatened that if the Han Dynasty did not withdraw, they would kill all these bloody horses. In the eyes of Emperor Wu of the Han Dynasty, they could not kill them! So Dawanguo chose its dozens of blood horses to form an alliance with the Han army, and then the Han Dynasty withdrew.
After obtaining many fine horses such as Dawan Blood Horse, Emperor Wu of the Han Dynasty quickly improved the breed of horses in the Central Plains and optimized the breed of Han horses. More importantly, the introduction of blood horses greatly improved the productivity and military equipment of the Han Dynasty.
But "Tianma" finally disappeared in the western part of China.
