《旧五代史·后唐·列传九》
立即命令宫苑使经办此事，但又担心郭崇韬会谏言劝止，派人对郭崇韬说： 今年酷热，我前不久在黄河上，五六月中，与敌对阵，行营低湿，骑上带甲衣的战马与敌人作战，总觉得清凉。
即令宫苑使经营之，犹虑崇韬有所谏止，使谓崇韬曰： 今年恶热，朕顷在河上，五六月中，与贼对垒，行宫卑湿，介马战贼，恆若清凉。
Immediately ordered the eunuch to do this matter, but worried that Guo Chongtao would persuade him to stop, and sent someone to tell Guo Chongtao: "It is very hot this year, I was on the Yellow River not long ago, in May and June, fighting against the enemy, the barracks were low and humid, riding on horseback wearing armor to fight with the enemy, I always felt cool."
