The difference between Kazak and Han nationality is even greater. Because we can look at it historically, because in the Tang Dynasty, Tibetans and Han people intermarried. For example, he thought of Princess Wencheng and Princess Jincheng. They brought the culture of the Central Plains and promoted the relationship between the Central Plains and Tubo, that is, today's Tibetans. Therefore, in terms of cultural identity, Han and Tibetan are closer. However, Kazakhs used to be in the western regions, which was not very close to the culture of the Central Plains. Therefore, if they have a greater relationship with the Han nationality, they must be Kazakhs.
