《三国志·吴书·王楼贺韦华传》
如果上空下乏，漕运供应不及，而北方敌人侵犯边界，即使让周公、召公重生，张良、陈平复出，也不能替陛下出谋划策以救危急，这一点是很清楚的！
若上下空乏，运漕不供，而北敌犯疆，使周、召更生，良、平复出，不能为陛下计明矣。
If the above is lacking and the transportation of food is insufficient, the enemy in the north invades the border, even if Zhou Gong and召公 are reborn, Zhang Liang and Chen Ping are resurrected, they cannot give advice to His Majesty to save the crisis, this is very clear!
