《百战奇略·第四卷·地战》
尚书令慕容镇则建议说： 倘若依照陛下的旨意去做，也必须是在平原地区每十里处驻扎一支部队，构筑好工事，以便利于使用骑兵为条件，因此，我们应当越出大岘山去迎战敌人，而一旦迎战不胜，还可以退守大岘山。
慕容镇曰： 若如圣旨，必须平原十里而军，军垒成，用马为便宜，出岘逆战而不胜，犹可退守。
Minister of the Imperial Secretariat Murong Zhen suggested: If we follow your Majesty's will, we must station troops every ten miles in the plain area, build fortifications, and facilitate the use of cavalry. Therefore, we should go beyond the Daishan Mountain to meet the enemy, and if we cannot win the battle, we can retreat back to the Daishan Mountain.
