无中生有

 
wú zhōng shēng yǒu (wu zhong sheng you)
something born from nothing (a fabrication; create an illusion that something exists when it doesn't or vice versa)

You use the same feint twice. Having reacted to the first and often the second feint as well, the enemy will be hesitant to react to a third feint. Therefore the third feint is the actual attack catching your enemy with his guard down.

Tang Dynasty China

During the An Lushan rebellion in 756 AD the Tang general Chang Shun was under siege by the forces of general Linghu Chao. Outnumbered twenty to one, the defending Tang forces soon ran out of arrows. To remedy this general Chang ordered his men to make straw dummies and to dress them in black uniforms. That night the dummies were lowered over the city walls by ropes, accompanied to the beat of war drums and gongs. General Linghu thought the enemy was launching a surprise night offensive and ordered his archers to shower the figures descending the walls with arrows. Once the dummies where riddled with arrows the Tang soldiers pulled them back up the walls and thus restored their supply of arrows.

The next day general Linghu realized he had been tricked and attacked the walls in revenge for being humiliated. That night the Tang again lowered the dummies but General Linghu ordered his men to ignore them believing it was the same trick to get more arrows. When general Chang saw that no one was firing at the straw dummies, he ordered that five hundred of his best troops be lowered instead. They made a lightning raid on the encamped soldiers who were caught completely by surprise. The siege was lifted and general Linghu's army fled the field.

Fei River

During the Battle of Fei River, Former Qin had an overwhelming manpower over Jin. But instead of backing down to defend, Jin attacked Former Qin forces early and formed wide formations, giving an illusion that Jin had the manpower to match Former Qin 's forces. Fu Jiān began planning his moves in fear, and later on ordered his vast forces to back out from the river banks. The low morale Former Qin troops went into chaos, and Jin came out of the battle victorious.

诳也,非诳也,实其所诳也①。少阴、太阴、太阳②。

【注释】

①诳也,非诳也,实其所诳也:诳,欺诈、诳骗。实,实在,真实,此处作意动词。句意为:运用假象欺骗对 方,但并非一假到底,而是让对方把受骗的假象当成 真象。

②少阴,太阴,太阳:此“阴”指假象,“阳”指真象。 句意为:用大大小小的假象去掩护真象。

【按语】

无而示有,诳也。诳不可久而易觉,故无不可以终无。无中生有,则由诳而真,由虚而实矣,无不可以败敌,生有则败敌矣,如:令狐潮围雍丘,张巡缚嵩为人千余,披黑夜,夜缒城下;潮兵争射之,得箭数十万。其后复夜缒人,潮兵笑,不设备,乃以死士五百砍潮营,焚垒幕,追奔十余里。

【解析】

此计的关键在于真假要有变化,虚实必须结合,一假到底,易被敌人发觉,难以制敌。先假后真,先虚后实,无中必须生有。指挥者必须抓住敌人已被迷惑的有利时机,迅速地以“真”、以“实”、以“有”,也就是以出奇制胜的速度,攻击敌方,等敌人头脑还来不及清醒时,即被击溃。

【探源】

无中生有,这个“无”,指的是“假”,是“虚”。这个“有”,指的是“真”,是“实”。无中生有,就是真真假假,虚虚实实,真中有假,假中有真。虚实互变,扰乱敌人,使敌方造成判断失误,行动失误。此计可分解为三部曲:第一步,示敌以假,让敌人误以为真;第二步,让敌方识破我方之假,掉以轻心;第三步,我方变假为真,让敌方仍误以为假。这样,敌方思想已被扰乱,主动权就被我方掌握。使用此计有两点应予注意:第一:敌方指挥官性格多疑,过于谨慎的,此计特别奏效。第二.要抓住敌方思想已乱迷惑不解之机,迅速变虚为实,变假为真,变无为有,出其不意地攻击敌方。

唐朝安史之乱时,许多地方官吏纷纷投靠安禄山、史思明。唐将张巡忠于唐室,不肯投敌。他率领二三千人的军队守孤城雍丘(今河南杞县)。安禄山派降将令狐潮率四万人马围攻雍丘城。敌众我寡,张巡虽取得几次突击出城袭击的小胜,但无奈城中箭只越来越少,赶造不及。无有箭只,很难抵挡敌军攻城。张巡想起三国时诸葛亮草船借箭的故事,心生一计。急命军中搜集秸草,扎成千余个草人,将草人披上黑衣,夜晚用绳子慢慢往城下吊。夜幕之中,令狐潮以为张巡又要乘夜出兵偷袭,急命部队万箭齐发,急如骤雨。张巡轻而易举获敌箭数十万支。令狐潮天明后,知已中计,气急败坏,后悔不迭。第二天夜晚,张巡又从城上往下吊草人。贼众见状。哈哈大笑。张巡见敌人已被麻痹,就迅速吊下五百名勇士,敌兵仍不在意。五百勇士在夜幕掩护下,迅速潜入敌营,打得令狐潮措手不及,营中大乱。张巡乘此机会,率部冲出城来,杀得分狐潮大败而逃,损兵折将,只得退守陈留(今开封东南)。张巡巧用无中生有之计保住了雍丘城。

【故事】

战国末期,七雄并立。实际上,秦国兵力最强,楚国地盘最大,齐国地势最好。其余四国都不是他们的对手。当时,齐楚结盟,秦国无法取胜。秦国的相国张仪是个著名谋略家,他向秦王建议,离间齐楚,再分别击之。秦王觉得有理,遂派张仅出使楚国。

张仪带着厚礼拜见楚怀王,说秦国愿意把商于之地六百里(今河南淅川、内江一带)送与楚国,只要楚能绝齐之盟。怀王一听,觉得有利可图:一得了地盘,二削弱了齐国,三又可与强秦结盟。于是不顾大臣的反对,痛痛快快地答应了。怀王派逢侯丑与张仪赴秦,签订条约。二人快到咸阳的时候,张仪假装喝醉酒,从车上掉下来,回家养伤。逢侯丑只得在馆驿住下。过了几天,逢侯丑见不到张仪,只得上书秦王。秦王回信说:既然有约定,寡人当然遵守。但是楚未绝齐,怎能随便签约呢?

逢侯丑派人向楚怀王汇报,怀王哪里知道秦国早已设下圈套,立即派人到齐国,大骂齐王,于是齐国绝楚和秦。

这时,张仪的“病”也好了,碰到逢侯丑,说:“咦,你怎么还没有回国?”逢侯丑说:“正要同你一起去见秦王,谈送商于之地一事。”张仪却说:“这点小事,不要秦王亲自央定。我当时已说将我的奉邑六里,送给楚王,我说了就成了。”逢侯丑说:“你说的是商于六百里!”张仪故作惊讶:“哪里的话!秦国土地都是征战所得,岂能随意送人?你们听错了吧!”

逢侯丑无奈,只得回报楚怀王。怀王大怒,发兵攻秦。可是现在秦齐已经结盟,在两国夹击之下,楚军大败,秦军尽取汉中之地六百里。最后,怀王只得割地求和。

怀王中了张仪无中生有之计,不但没有得到好处,相反却丧失大片国土。
