At the end of The Art of War · Initial Estimations, Sun Tzu put forward a timeless strategic maxim respected by strategists worldwide for over 2,500 years:
This is the famous military principle: More planning leads to victory, while less planning leads to defeat.
What Is “Temple Calculation” in Ancient Warfare?
Sun Tzu named pre-war strategic planning Temple Calculation (Miao Suan). In ancient China, before launching any large-scale war, monarchs and top generals would gather in the royal ancestral temple to evaluate all battlefield factors comprehensively: enemy troop strength, terrain advantages, grain supplies, internal unity, weather conditions and potential risks.
Only after completing full deliberation and strategic deduction would the army march into battle. With thorough pre-war assessment, commanders could fight with full confidence and grasp every battlefield initiative.
As time went by, military planning was no longer limited to royal temples. Generals formulated battle strategies inside military tents on the frontline, which evolved into the well-known Chinese idiom: plan strategies within a military tent, and win decisive victories a thousand miles away.
Emperor Gaozu of Han, Liu Bang, once spoke highly of his chief advisor Zhang Liang:
This famous comment fully proves that deliberate pre-war planning is the core foundation of all victories, whether in ancient wars or modern competitions.
The Eternal Truth: Victory Is Decided Before the War Starts
Sun Tzu pointed out a universal truth across thousands of years: The final outcome of a war is never determined by bloody head-on fighting on the battlefield. Instead, victory or defeat is already settled before troops draw their weapons.
Every sudden battlefield victory is never a lucky accident, but the inevitable result of complete pre-war deduction. Every unexpected defeat is rarely caused by poor combat performance, but stems from careless and insufficient strategic planning beforehand.
Ancient War Cases: Sharp Contrast Between Full Planning and Blind Combat
Case 1: Wu Zixu’s Well-Calculated Plan to Exhaust Chu (Well-Planned War = Easy Victory)
During the Spring and Autumn Period, the State of Chu boasted vast territory and overwhelming military strength, far stronger than the rising State of Wu. King Helü of Wu intended to conquer Chu but avoided blind full-scale attacks after rational temple calculation.
Wu Zixu made comprehensive pre-war analysis: Chu had numerous conflicting ministers without unified command, and all officials dared not take military responsibility. A direct full-army attack would only exhaust Wu’s people and resources with little gain.
Based on thorough overall calculation, Wu Zixu designed the famous fatigue strategy: split Wu’s army into three mobile units to launch rotating surprise raids on Chu’s border. Wu’s troops retreated instantly once Chu’s army marched out, and struck again right after Chu’s troops returned to rest.
This well-calculated tactic forced Chu’s army to shuttle back and forth endlessly, draining its manpower, grain and morale. Every military action of Wu followed preset strategic plans without blind impulsive attacks. Thanks to sufficient pre-war calculation, Wu weakened powerful Chu at minimum cost and finally captured Chu’s capital in the Battle of Bo Ju. This is the perfect proof of more calculation brings victory.
Case 2: Cao Jiu’s Blind Combat Without Planning (No Calculation = Total Collapse)
In contrast, Cao Jiu, the general of Chu during the Chu-Han Contention, suffered a devastating defeat due to zero strategic planning. Xiang Yu strictly ordered Cao Jiu to hold the city and refuse all battles. However, Cao Jiu made no overall battlefield judgment, lost his temper after continuous insults from the Han army, and impulsively ordered his army to cross the Si River to fight.
He never calculated enemy ambush risks, troop deployment changes and battlefield terrain. His blind and impulsive attack led to a total rout of Chu’s army, and he finally committed suicide in shame. His failure fully verifies Sun Tzu’s warning: those with no calculation are doomed to complete defeat.
Modern Enlightenment: Beyond Battlefields
Sun Tzu’s wisdom of sufficient pre-war planning is never limited to ancient military wars. It still carries strong guiding significance for modern business competition and personal life choices.
Enlightenment for Business Competition
Top enterprises never win market competition relying on on-the-spot emergency responses or blind passion. Their long-term market dominance comes from sufficient pre-action calculation: full research on market trends, comprehensive assessment of potential risks, accurate judgment of industrial opportunities and clear layout of competitive strategies. So-called business wisdom is exactly modern temple calculation.
Enlightenment for Personal Life
In personal life, thorough planning represents rare calm and rationality. Facing critical choices including career development, city relocation and life planning, we need to deduce all possible results in advance, clarify our inner pursuits, evaluate long-term hidden costs of each choice, and reserve buffer space for unexpected changes.
Sadly, most people fall into the trap of acting blindly without thinking. We make hasty decisions out of anxiety, and use busy hard work to cover lazy thinking. Blind action without prior deliberation only leads to repeated mistakes and endless trial and error, rather than essential life breakthroughs.
Conclusion: The Strongest Competitiveness Is Deep Thinking
Sun Tzu’s millennium-old philosophy delivers a straightforward and powerful lesson:
- People with sufficient planning seize initiative and control the overall situation;
- People with insufficient planning can only respond passively to changes;
- People with no planning at all will face inevitable failure.
Deep thinking itself is the most core and powerful competitiveness. The wisest way to win is to secure victory before taking action. When you calm down, overview the overall situation and make thorough planning, you have already won half the battle in advance.
