The name Know Your Enemy in Chinese / Japanese...

道天地將法 is a list of five key points to analyzing your situation from the first chapter of Sun Tzu's Art of War.

This reads like a 5-part military proverb. Sun Tzu says that to sharpen your skills, you must plan. To plan well, you must know your situation. Therefore, you must consider and discuss the following:

1. Philosophy and Politics: Make sure your way or your policy is agreeable among all of your troops (and the citizens of your kingdom as well). For when your soldiers believe in you and your way, they will follow you to their deaths without hesitation and will not question your orders.

2. Heaven/Sky: Consider climate / weather. This can also mean considering whether God is smiling upon you. In the modern military, this could be waiting for clear skies so that you can have air support for an amphibious landing.

3. Ground/Earth: Consider the terrain in which the battle will take place. This includes analyzing defensible positions, and exit routes, while using varying elevations to your advantage. When you plan an ambush, you must know your terrain and the best location from which to stage that ambush. This knowledge will also help you avoid being ambushed, as you will know where the likely places in which to expect an ambush from your enemy.

4. Leadership: This applies to you as the general and your lieutenants. A leader should be smart and be able to develop good strategies. Leaders should keep their word, and if they break a promise, they should punish themselves as harshly as they would punish subordinates. Leaders should be benevolent to their troops, with almost a fatherly love for them. Leaders must have the ability to make brave and fast decisions. Leaders must have steadfast principles.

5. [Military] Methods: This can also mean laws, rules, principles, models, or systems. You must have an efficient organization in place to manage both your troops and supplies. In the modern military, this would be a combination of how your unit is organized and your SOP (Standard Operating Procedure).

Notes: This is a simplistic translation and explanation. Much more is suggested in the actual text of the Art of War (Bing Fa). It would take a lot of study to master all of these aspects. In fact, these five characters can be compared to the modern military acronyms such as BAMCIS or SMEAC.

CJK notes: I have included the Japanese and Korean pronunciations but in Chinese, Korean and Japanese, this does not make a typical phrase (with subject, verb, and object) it is a list that only someone familiar with Sun Tzu’s writings would understand.

敵を知り己を知る is the Japanese version of “know your enemy, know yourself.”

There is a longer version of this proverb that adds, “...and you can win 100 battles.”

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

知彼知己百戰不殆 is from Sun Tzu's (Sunzi's) Art of War. It means that if you know and understand the enemy, you also know yourself, and thus with this complete understanding, you cannot lose.

This proverb is often somewhat directly translated as “Know the enemy and know yourself, and you can fight a hundred battles without defeat.”

It can also be translated as “If you know both yourself and your enemy, you can come out of hundreds of battles without danger,” or “Know your enemy, know yourself, and your victory will not be threatened.”

敵を知り己を知れば百戦危うからず is the longer/full Japanese version of this proverb. This means “Know your enemy, know yourself, and you will not fear a hundred battles.”

Others will translate this as “Know thy enemy, know thyself, yields victory in one hundred battles.”

Note: Because this selection contains some special Japanese Hiragana characters, it should be written by a Japanese calligrapher.

闇打狐狸明打狼 is a Chinese proverb that translates as: Hunt foxes stealthily, [and] hunt wolves openly [just as they do].

Figuratively, this means:
Different opponents require different appropriate strategies.

This is a suggestion that you should know your enemy and know that each enemy is different, therefore requires a specialized approach (attack).
