《新唐书·列传·卷三十六》
唐休璟认为不能这样，呈递奏疏说： 丰州控制黄河阻止敌人，被称为山川屏障环绕的军事要地，从秦朝、汉朝以来，一直在那里设置郡县。
休璟以为不可，上疏曰： 丰州控河遏寇，号为襟带，自秦、汉以来，常郡县之。
Tang Xiujing believed that this would not work and submitted a memorial stating that: Fengzhou commanded the Yellow River to block the enemy and was known as a military stronghold surrounded by natural barriers. Counties and prefectures had been established there since the Qin and Han dynasties.
