党项族成为唐朝的边境祸患，朝廷调发诸道兵攻讨，连年未获成功，而戌边的给养却输送不已；右补阙孔温裕向唐宣宗上疏进行谏阻，词语痛切，唐宣宗发怒，将孔温裕贬为柳州司马。

The Tangui became a scourge for the Tang Dynasty on the border. The imperial court sent troops from all the circuits to conquer them, but after many years without success, the support of the border forces continued. Right assistant censor Kong Wenyu wrote a memorial to Emperor Tang Xuanzong to advise against the expedition, since his words were so cutting, Emperor Tang Xuanzong became angry and demoted Kong Wenyu to Sima of Liuzhou.
