Today , the 56 nationalities, including the Han nationality, live on China's 9.6 million square kms of land territory. Along with the Han people, these minorities have added to the profound Chinese civilization with their own fascinating cultures. Their beautiful costumes with unique accessories, diverse food customs, fascinating traditions, celebrations and history represent significant elements of Chinese civilization.
