兵bīng法fǎ

知zhī有yǒu所suǒ甚shèn爱ài，知zhī有yǒu所suǒ不bù足zú爱ài，可kě以yǐ用yòng兵bīng矣yǐ。故gù夫fū善shàn将jiāng者zhě，以yǐ其qí所suǒ不bù足zú爱ài者zhě，养yǎng其qí所suǒ甚shèn爱ài者zhě。士shì之zhī不bù能néng皆jiē锐ruì，马mǎ之zhī不bù能néng皆jiē良liáng，器qì械xiè之zhī不bù能néng皆jiē坚jiān固gù也yě，处chù之zhī而ér已yǐ矣yǐ。兵bīng之zhī有yǒu上shàng中zhōng下xià也yě，是shì兵bīng之zhī有yǒu三sān权quán也yě。孙sūn膑bìn有yǒu言yán曰yuē：「以yǐ君jūn下xià驷sì，与yǔ彼bǐ上shàng驷sì；取qǔ君jūn上shàng驷sì，与yǔ彼bǐ中zhōng驷sì；取qǔ君jūn中zhōng驷sì，与yǔ彼bǐ下xià驷sì。」此cǐ兵bīng说shuō也yě，非fēi马mǎ说shuō也yě。下xià下xià之zhī不bù足zú以yǐ与yǔ其qí上shàng也yě，吾wú既jì知zhī之zhī矣yǐ，吾wú既jì弃qì之zhī矣yǐ。中zhōng之zhī不bù足zú以yǐ与yǔ吾wú上shàng，下xià之zhī不bù足zú以yǐ与yǔ吾wú中zhōng，吾wú不bù既jì再zài胜shèng矣yǐ乎hū？得dé之zhī多duō于yú弃qì也yě，吾wú斯sī从cóng之zhī矣yǐ。彼bǐ其qí上shàng之zhī有yǒu三sān权quán也yě。三sān权quán也yě者zhě，以yǐ一yī权quán而ér致zhì二èr者zhě也yě。管guǎn子zi曰yuē：「攻gōng坚jiān则zé瑕xiá者zhě坚jiān，攻gōng瑕xiá则zé坚jiān者zhě瑕xiá」。呜wū乎hū！不bù从cóng其qí瑕xiá而ér攻gōng之zhī，天tiān下xià皆jiē强qiáng敌dí也yě。
