东汉建武十五年至中平五年的１５０年间，朝廷残酷的民族压迫和歧视政策引起了南方、西南各少数民族的不断反抗。为镇压反抗，官方与这些少数民族进行了大小近４０战。在战争中，由于少数民族互相配合、联合作战，官军劳师远征，收效甚微，损失特大。本文由此揭示出：民族政策的正确与否，是关乎国家兴亡盛衰的大事，战争并非解决民族关系问题的良策。 During the 15 years from the establishment of the Eastern Han Dynasty to the 15th year of the Five-Year Plan of Zhongping, the brutal policy of ethnic oppression and discrimination in the imperial court caused repeated resistance by the ethnic minorities in the south and southwest. In order to suppress the resistance, the government carried out nearly 40 battles with these minorities in size. In the war, due to the mutual cooperation and joint operations of ethnic minorities, the expedition of the officers and men in the army was very ineffective and greatly damaged. This article reveals that the correctness of the national policy is a major event concerning the ups and downs of the nation’s rise and fall. War is not a good solution to the issue of ethnic relations.
