《将苑·卷二·东夷》
东夷这样不开化的少数民族，不守礼义，勇猛强悍，凶狠善战，他们依山傍海，凭借险要的地形，有较强的自我保护、对外防御的能力。
东夷之性，薄礼少义，捍急能斗，仪山堑海，凭险自固。
The Eastern Yi, such a backward minority, did not follow etiquette, they were brave and tough, fierce and good at fighting. They lived near mountains and the sea, and with the advantage of dangerous landscapes, had relatively strong ability of self-protection and defense against foreign enemies.
