I live in the Republic of Kazakhstan. The capital of Kazakhstan is Astana. Our state has 3 national simbols. They are a flag, heads and national anthem. We have plenty of national holidays, such as Nauryz, Oriental New Year, the Day of Independence and the like, and traditions, for example Kazakh people have a long tradition of peace, tolerance and co-existence. Children learn hospitality and respect from a very young age. All generations esteem and take care of old representatives of the nation.
