《太平广记·卷五·神仙五》
墨子解下自己的衣带放在桌上假设是宋国的都城，又摘下头巾假设是宋国守城的士兵和武器，公输般就摆布他攻城的武器和战术。
墨子解带为城，以幞为械，公输般乃设攻城之机。
Mozi placed his waistband on the table and pretended it was the capital city of Song; he also took off his headband and pretended it was the soldiers guarding Song and their weapons, while Gongshu Ban arranged the weapons and tactics he'd use to attack the city.
