《论衡·卷四·书虚篇》
齐桓公娶姑姊妹七个人，罪恶超过夏桀、商纣，罪过比胡亥使秦灭国和王莽篡权还严重。
桓公妻姑姊七人，恶浮於桀、纣，而过重於秦、莽也。
Duke Huan of Qi married his seven aunts and sisters, a crime worse than those of Jie of Xia and Zhou of Shang, and more serious than the transgressions of Hu Hai that resulted in the fall of Qin and Wang Mang's usurpation of the throne.
