春秋战国时期夷、夏之间的关系发生很大的转折,出现中国历史上第一次名族大融合的局面。春秋初期,夷、夏矛盾激化,夷夏观念强化,表现在对夷狄采取镇压还是安抚的政策。经过春秋战国三百年变迁。夷夏对立的局面逐渐淡化,出现了统一的趋势,并实现了局部统一,“中国”的含义与范围都有了明显的发展,为以后秦的大一统奠定了坚实的基础。 During the Spring and Autumn Period and the Warring States Period, the relations between the two countries witnessed a great turnaround and the first large-scale integration in the history of China appeared. In the early Spring and Autumn Period, the intensification of contradictions between the barbarians and the Chinese people and the strengthening of the concept of barbarians and the barbarians in the summer represented the policy of suppressing or reassuring the barbarians. After three centuries of the Spring and Autumn Warring States change. The opposition to Yixia gradually diminished, a trend of unification emerged, and a unified situation was achieved. The meaning and scope of “China” have all evolved significantly, laying a solid foundation for the future unification of Qin.
