What nationality is the "Khitan" that gives Song a headache?

The Khitan nationality has a glorious history in ancient times, which also made the powerful Song State have a headache at that time. However, with the passage of time, the Khitans seem to have no news. The Khitans were originally nomadic people, and with the passage of time, the Khitans also migrated to Iran and Mongolia, so today's Iran is the descendant of the Khitans.

The rise of qidan nationality.

The Khitan nationality has a very glorious history, but with the change of time, they gradually withdrew from the historical stage, but this nationality has not disappeared. Maybe you don't think so. According to historical research, the Khitan nationality rose in the early years of the Tang Dynasty and was a tribal alliance with hunting as the main mode of production. In the early days of the Tang Dynasty, the Khitan people always obeyed the management of the Tang Dynasty. Later, during the Wu Zetian period, the Khitans rebelled and were finally suppressed. Later, Qidan broke away from the Tang Dynasty and became the primary enemy of the Central Plains.

What's the difference between the Khitans and the Han people?

Since the founding of Liao State, the Khitans have absorbed the rules and regulations of Tang and Song Dynasties and studied the cultural customs of the Central Plains. By the end of Liao Dynasty, her emperor had mastered Qing Dynasty, chess, calligraphy and painting. Rulers in the Jin Dynasty generally practiced grammaticalization, and the Qidan nationality in the Jin Dynasty also absorbed more Chinese culture. After the downfall of the State of Jin, people could not find the difference between them and other Han nationalities except the Yalu and Xiao nationalities controlled by the Khitan.

The demise of the Khitan.

Liao was destroyed, but it still left a trail. Thousands of people affected by the disaster were brought to Central Asia, forming the Western Liao Dynasty, which once became one of the most powerful countries in Central Asia. However, the Western Liao Dynasty eventually became the dust of a distant country, destroyed by the rising Jin State, by the rising Mongolia, and then by Mongolia. But the Khitan, a famous nation for hundreds of years, has not disappeared. Once a scientist made a special investigation on the Khitan nationality, and finally found the kingdom of Khitan, which developed in two directions. First, the Khitans moved westward, and in today's Iran, they gradually merged into the local ethnic groups. The second is to join the Central Plains.
