Add to this the facts that our guardpasses and barriers are lacking in strength, that our prohibitions [against trade] are full of holes, and fine gold and good iron are in the hands of the enemy, while they also have renegades from Han to serve them as masters of strategy; then in the sharpness of weapons and the clash of horse they are more dangerous than were the Xiongnu.\" §REF§Emperor Huan and Emperor Ling, Xiping6: 177 AD E from Zizhi tongjian by Sima Guang, translated by Rafe De Crespigny, Internet edition 2003§REF§ Replaced the original translation of the Chinese source with a better translation, which translates the Xiongnu as such rather than as \"huns\" for example."
