Uyghurs are one of the ancient nationalities of China who established kingdoms in the 7th-9th centuries. They celebrate the spring festival of Nowruz, which originated in ancient Mesopotamia and is not a religious holiday but a celebration of the renewal of nature. During Nowruz, Uyghurs gather in public places wearing traditional clothes and engage in singing, dancing, games, and performances to entertain the crowds. Special foods are also cooked and shared as part of the celebrations.
