Translation: In the use of arms there is a saying: I dare not act as the one who takes the offensive, but prefer to be the one who remains on the defensive; I dare not advance an inch, but prefer to retreat a foot.
Analysis: This is the core of Laozi's military philosophy—defense as offense, retreat as advance. The asymmetry of "advancing an inch, retreating a foot" carries profound meaning: even when advancing, one does so with extreme caution (only an inch), yet retreat is measured in feet (strategic withdrawal to gain depth). Heshang Gong made this concrete: "Invading others' territory and seizing their wealth is advancing; closing the gates and defending the city is retreating." This principle is not merely military wisdom but a philosophy of life—better to yield generously than to contend excessively.
Similar views: Heshang Gong: "主，先也。不敢先举兵。客者，和而不倡。用兵当承天而后动。" ("Host means taking the initiative. One dares not be the first to raise arms. The guest is one who responds harmoniously without instigating. In using arms, one should follow Heaven's mandate before acting.")
Translation: In the use of arms there is a saying: I dare not act as the host (fighting on home ground / the instigator), but prefer to be the guest (the defender); I dare not advance an inch, but prefer to retreat a foot.
Analysis: In ancient military contexts, "host" (主) and "guest" (客) carried special meanings—the "host" is the instigator of war or the side fighting on home territory, while the "guest" is the side compelled to respond or the expeditionary force. Laozi inverts conventional wisdom: normally the host is considered to have the advantage, but Laozi prefers to be the "guest"—not initiating war, not invading others' territory, engaging only in self-defense when absolutely necessary.

Translation: This is called: marching as if there were no formations; baring the arm as if there were no arm; confronting the enemy as if there were no enemy; grasping weapons as if there were no weapons.
Analysis: The four instances of "without" (无) compose an ultimate description of "formless tactics": the army moves so covertly that it appears to have no formations (marching without formations); striking with such lightness that it seems as though there are no arms (baring arms without arms); facing the enemy with such composure that it is as though there is no enemy (confronting without enemy); wielding weapons so naturally that it appears there are no weapons (grasping without weapons). This is the military philosophy of "overcoming the tangible through the formless"—making it impossible for the enemy to locate your position, fathom your intentions, or assess your strength.
Similar views: Wang Bi: "言以谦退哀慈，不敢为物先，用战犹行无行，攘无臂，执无兵，扔无敌也。" ("This means that through humility, compassion, and reluctance to take the lead, even in war one marches without formations, bares arms without arms, grasps weapons without weapons, and confronts the enemy without an enemy.")
Translation: This is called: marching without the air of killing (marching without formations); baring the arm yet unable to strike (baring arms without arms); facing the enemy yet unable to bear enmity (confronting without enemy); grasping weapons yet unable to bear using them (grasping without weapons).
Analysis: Heshang Gong's interpretation imbues this passage with humanitarian coloring—the four instances of "without" are not tactical formlessness but psychological reluctance: pitying the enemy's people who "suffer under Heaven's punishment, subjected to an unrighteous ruler" (Heshang Gong's words). Though compelled to fight, the heart is filled with compassion. Baring the arm yet unable to bear striking with force, grasping weapons yet unable to bear inflicting harm—this is the posture of the compassionate in war.
Similar views: Heshang Gong: "虽欲执持之，若无兵刃可持用也。何者？伤彼之民罹罪于天，遭不道之君，愍忍丧之痛也。" ("Though one wishes to hold the weapons, it is as if there are no blades to wield. Why? Because one grieves that the enemy's people suffer under Heaven's punishment, subjected to an unrighteous ruler, and one feels compassion for the pain of their losses.")
Translation: No disaster is greater than underestimating the enemy; underestimating the enemy nearly brings the loss of my Three Treasures.
Analysis: Wang Bi identifies "treasures" (宝) as referring to the "Three Treasures" of Chapter 67—compassion (慈), frugality (俭), and not daring to be first in the world (不敢为天下先). Underestimating the enemy means losing all three: one is no longer compassionate (disregarding the lives of soldiers), no longer frugal (wasting military resources), and rushes forward recklessly (violating "not daring to be first in the world"). The fundamental reason an arrogant army inevitably fails is not a technical error in judgment, but a threefold collapse of moral qualities.
Similar views: Wang Bi: "宝，三宝也，故曰几亡吾宝。" ("'Treasures' refers to the Three Treasures, hence it says 'nearly loses my treasures.'")
Translation: No disaster is greater than underestimating the enemy; underestimating the enemy brings one close to losing one's very life.
Analysis: Heshang Gong interprets "treasure" (宝) as "self" (身)—one's own life. This reading is more direct: the ultimate price of underestimating the enemy is death. "Nearly loses my treasure" = "death is not far away." This interpretation applies to everyone—not just the ruler's Three Treasures, but every person's most fundamental treasure—their own life.
Similar views: Heshang Gong: "几，近也。宝，身也。欺轻敌者，近丧身也。" ("'Nearly' means close. 'Treasure' means the self. One who underestimates the enemy is close to losing one's life.")
Translation: No disaster is greater than underestimating the enemy; underestimating the enemy nearly brings the loss of my most precious possession (compassion).
Analysis: Wang Bi offers a deeper layer of interpretation: "言吾哀慈谦退，非欲以取强，无敌于天下也。不得已而卒至于无敌，斯乃吾之所以为大祸也。" ("I am sorrowful, compassionate, and humble in retreat, not seeking to gain supremacy or to be without rival in the world. Being compelled to the point of becoming invincible—this is precisely what constitutes the greatest disaster.")—The "great disaster" Laozi speaks of is not merely the military defeat caused by underestimating the enemy, but rather that when you become so powerful as to be "without rival," you may grow arrogant and thereby lose your compassionate heart. Power itself is a test—remaining compassionate while powerful is the most difficult cultivation.
Similar views: Wang Bi: "不得已而卒至于无敌，斯乃吾之所以为大祸也。" ("Being compelled to the point of becoming invincible—this is precisely what constitutes the greatest disaster.")
Translation: Therefore, when two armies confront each other in equal strength, the side that grieves (fighting only out of necessity) shall prevail.
Analysis: This is the origin of the famous saying "an army burning with righteous indignation is bound to win" (哀兵必胜). The power of "grief" (哀) lies in: (1) the side compelled to fight has a stronger moral foundation, and its soldiers are more united; (2) those in sorrow have no retreat and will fight to the death; (3) the grieving side cherishes life—both their own and their opponents'—and therefore makes more cautious and thorough decisions. The belligerent side, by contrast, acts rashly and recklessly, ultimately meeting defeat.
Similar views: Wang Bi: "哀者，必相惜而不趣利避害，故必胜。" ("Those who grieve will surely cherish one another and not chase after profit or flee from harm, and therefore will surely prevail.")
Translation: Therefore, when two armies confront each other, the side that is compassionate shall prevail.
Analysis: Taking "grief" (哀) in the sense of "compassion"—"the grieving side prevails" is essentially "the compassionate side prevails," directly echoing Chapter 67's "with compassion, one can be courageous" (慈故能勇) and "in battle, one shall be victorious" (以战则胜). The compassionate commander cherishes soldiers (not recklessly ordering charges), shows empathy for the people (not exhausting the populace), and knows when to stop and retreat (not overreaching for glory). Compassion is not weakness but the most profound source of strength.
Similar views: Heshang Gong: "哀者慈仁，士卒不远于死。" ("The grieving are compassionate and benevolent, and their soldiers are willing to die for the cause.") This resonates with Chapter 67's "with compassion, one can be courageous" (慈故能勇).
Translation: Therefore, when opposing armies clash, the side that deeply suffers over war shall surely prevail.
Analysis: The deepest reading—"grief" (哀) is not merely sorrow or compassion, but a profound anguish over and opposition to war itself. Only those who truly understand the horror of war can make the wisest military decisions—because they fight not for glory or profit, but to end suffering as quickly as possible. Such a person will not advance recklessly, will not underestimate the enemy, and will not escalate the war, and therefore will ultimately prevail.
Similar views: This resonates deeply with Chapter 31: "夫兵者，不祥之器也……杀人之众，以悲哀泣之，战胜以丧礼处之" ("Arms are instruments of ill omen… When great numbers are killed, one should weep over them with sorrow; when victorious in battle, one should observe the rites of mourning").

[Core Divergences]
Chapter 69 is the concentrated expression of Laozi's military philosophy and the origin of the famous saying "an army burning with righteous indignation is bound to win" (哀兵必胜). The chapter is structured as follows: first, a military maxim is quoted (dare not be the host but prefer to be the guest, advance an inch and retreat a foot); then the four instances of "without" depict formless tactics / the posture of reluctance; next, the greatest military taboo is identified (underestimating the enemy); and finally, the chapter concludes with "the grieving side shall prevail." This chapter, together with Chapter 67 (the Three Treasures) and Chapter 68 (the virtue of non-contention), forms a continuous three-chapter exposition of military philosophy, creating a complete chain of thought: compassion → not warlike / not wrathful / not contending → being the guest and retreating a foot → marching without formations → the grieving side prevails. The core divergence centers on the character "grief" (哀): Wang Bi emphasizes "cherishing one another and not chasing after profit or fleeing from harm" (the quality of a commander's decision-making), while Heshang Gong emphasizes "compassionate and benevolent, soldiers willing to die for the cause" (cohesion of military morale). The two respectively argue for "the grieving side shall prevail" from the angles of a commander's decision-making quality and the cohesion of military spirit. Worth deep reflection is "underestimating the enemy nearly costs me my treasures"—Wang Bi uniquely points out that the greatest danger is not being defeated by the enemy, but losing one's compassionate heart because of being too powerful. This elevates the military question to the level of spiritual cultivation—remaining humble while powerful, remaining sorrowful while invincible—this is what it truly means to be skilled in warfare.
