Why did Kazakhs, a nation that emphasizes lifelong marriage, come to China?

Not Kazakhs to China. Kazak is a nomadic people, and they migrate with abundant aquatic plants, which makes this people form a nomadic migration custom. Mongolia-Russian-China-and several countries in Central Asia have patches of mountain grasslands and woodlands, which are also good geographical environments for animal husbandry, so-in the above areas. Kazakh people live together. Kazak is a cheerful and unrestrained nation, which also enables this nation to get along well with other ethnic groups, thus forming a form of living where people live in mixed communities and live in small communities. Therefore, there are a large number of Kazakhs living in Yili-Tacheng-Altay, China. They live in harmony with all ethnic groups, from China to the world, and stand proudly among all ethnic groups in the world. They are a country with a glorious history.
