中国苍茫大地，幅员辽阔，民族众多，历史上各民族在政治、经济、文化上相互融合，但这种融合并不能完全泯灭各民族的特性，尤其是与外界接触稀少的民族。纵观历史文化的长河，各民族在日常的物质生活与精神生活中，语言、行为都有体现着自己的喜好、风尚、信仰、习惯、禁忌等? China’s vast land is vast in size and has many nationalities. Historically, all ethnic groups have merged politically, economically and culturally with each other. However, this integration does not completely destroy the characteristics of various ethnic groups, especially those with few contacts with the outside world. Throughout the long history of history and culture, all ethnic groups have their own preferences, customs, beliefs, habits and taboos in their everyday material life and spiritual life.
