《资治通鉴·后唐纪·后唐纪一》
只要忧虑王彦章侦察到我们的情况，直接逼近我们，到那时我们的城还修不好。希望陛下召募敢死的士卒，每天让他们挑动敌人出动来牵制他们，如果王彦章十几天不向东去，城垒就可以修好。 
但虑彦章诇知，径来薄我，城不能就，愿陛下募敢死之士，日令挑战以缀之，苟彦章旬日不东，则城成矣。 
The only concern is that Wang Yanzhang will scout our movements and come straight to us. By then, our city will not be completed. I hope that Your Majesty will recruit dare-to-die soldiers and have them provoke the enemy into action every day. If Wang Yanzhang does not go east for ten days, our fortifications can be completed.
