《北齐书·列传·卷五十》
当初在天保年间，显祖从晋阳回到邺，装疯的僧人阿秃师站在路中大叫，喊着显祖的名字说： 阿那瓖最终要破灭你的国家。 当时茹茹国主阿那瓖在塞北很强盛，显祖对他尤其顾忌，所以每年都派兵征讨，最后灭亡齐国的正好是阿那肱。
初天保中，显祖自晋阳还邺，阳愚僧阿秃师于路中大叫，呼显祖姓名云： 阿那终破你国。 是时茹茹主阿那在塞北强盛，显祖尤忌之，所以每岁讨击，后亡齐者遂属阿那肱云。
At the time of the Tianbao era, when Emperor Xianzong returned to Ye from Jinyang, the mad monk Atusi stood in the middle of the road and shouted, calling out Emperor Xianzong’s name: “Anagui will ultimately destroy your nation.” At that time, the Rouran ruler Anagui was very powerful in the north, and Emperor Xianzong was especially wary of him, so he sent troops to attack him every year. In the end, it was Anagong who destroyed the Qi nation.
