Translation: The Tao (道) gives birth to primordial Qi (气), primordial Qi differentiates into Yin and Yang, Yin and Yang interact to produce harmonizing Qi (the third element), and harmonizing Qi generates the myriad things.
Analysis: Heshanggong's cosmogonic interpretation. Tao → primordial Qi → Yin and Yang → harmonizing Qi → myriad things—this forms a clear chain of cosmic creation. "Three" refers to the three Qi of Yin, Yang, and Harmony, or the Three Powers of Heaven, Earth, and Humanity. His commentary states: "天地人共生万物也，天施地化，人长养之也" ("Heaven, Earth, and Humanity together give birth to all things; Heaven bestows, Earth transforms, and Humanity nurtures"). This interpretation became the foundation for later Daoist cosmology.
Similar views: Heshanggong: "道使所生者一也" ("What the Tao gives birth to is the One"). "一生阴与阳也" ("The One gives birth to Yin and Yang"). "阴阳生和、清、浊三气" ("Yin and Yang give birth to the three Qi of harmony, clarity, and turbidity"). "天地人共生万物也" ("Heaven, Earth, and Humanity together give birth to all things").
Translation: The Tao (道) gives rise to a unified whole (One); the unified whole differentiates into opposites (Two); the opposites interact to produce new entities (Three); and thus the myriad things ceaselessly come into being.
Analysis: Wang Bi's ontological interpretation is more abstract: "由无乃一，一可谓无，已谓之一，岂得无言乎。有言有一，非二如何，有一有二，遂生乎三，从无之有，数尽乎斯" ("From Non-being comes the One; the One may be called Non-being, yet once we call it 'One,' how can language be avoided? Once there is language and the One, how can there not be Two? Once there is One and Two, Three inevitably arises—from Non-being to Being, all numbers are exhausted herein"). Once one moves from "Non-being" (the Tao) into "Being" (the One), distinctions inevitably arise (Two), and with distinctions comes further multiplicity (Three), extending to the myriad things. The numbers are not literal but represent the logical unfolding from Non-being to Being.
Similar views: Wang Bi: "万物万形，其归一也，何由致一，由于无也。从无之有，数尽乎斯" ("The myriad things with their myriad forms all return to the One; how does one arrive at the One? Through Non-being. From Non-being to Being, all numbers are exhausted herein").
Translation: The myriad things all carry Yin on their backs and embrace Yang in their arms; the two Qi clash and surge against one another, achieving harmony.
Analysis: The most widely accepted interpretation. All things contain both Yin and Yang attributes—Yin on the outside (carried on the back) and Yang on the inside (embraced). The two Qi are not in static opposition but in constant dynamic interaction, achieving dynamic equilibrium (harmony) through their movement. Heshanggong comments: "万物中皆有元气，得以和柔" ("Within all things there is primordial Qi, by which they attain harmony and suppleness")—primordial Qi (harmonizing Qi) within all things maintains the balance of Yin and Yang.
Similar views: Heshanggong: "万物无不负阴而向阳，回心而就日" ("All things without exception carry Yin and face Yang, turning their hearts toward the sun"). "万物中皆有元气，得以和柔" ("Within all things there is primordial Qi, by which they attain harmony and suppleness").
Translation: The myriad things carry Yin on their backs and embrace Yang; through empty, vacuous Qi they achieve harmony.
Analysis: Here "冲" is taken in the sense of "empty, vacuous." Between Yin and Yang there must be an "empty" intermediate space to mediate—just as in Chapter 4, "道冲而用之或不盈" ("The Tao is empty, yet in use it is never exhausted"). Harmony is not the direct collision of Yin and Yang, but rather the equilibrium maintained by that "empty" space between them. This interpretation carries greater metaphysical depth.

Translation: What people detest are the titles "orphaned," "desolate," and "unworthy," yet lords and princes adopt these very terms as their own designations.
Analysis: Everyone detests solitude, scarcity, and unworthiness—yet lords and princes deliberately take these as their titles. This embodies the wisdom of "dwelling below" and "maintaining softness." The higher one's position, the more one should use the lowliest titles as a reminder to remain humble. Heshanggong comments: "孤寡不毂者，不祥之名，而王公以为称者，处谦卑，法空虚和柔" ("'Orphaned,' 'desolate,' and 'unworthy' are inauspicious names, yet lords and princes adopt them as titles because they dwell in humility, emulating emptiness, harmony, and suppleness").
Similar views: Heshanggong: "孤寡不毂者，不祥之名，而王公以为称者，处谦卑，法空虚和柔" ("'Orphaned,' 'desolate,' and 'unworthy' are inauspicious names, yet lords and princes adopt them because they dwell in humility, emulating emptiness, harmony, and suppleness"). Chapter 39 contains the same discussion.
Translation: Therefore, things are sometimes diminished yet thereby increased, and sometimes increased yet thereby diminished.
Analysis: A core proposition of dialectical thought. Reduction can lead to increase (as when lords and princes adopt humble titles yet gain greater reverence), and increase can lead to reduction (as when insatiable greed invites disaster). Heshanggong's commentary is direct: "引之不得，推之必还" ("Pull at it and you cannot hold it; push it away and it inevitably returns"). "夫增高者志崩，贪富者致患" ("Those who pile up height court collapse in their ambitions; those who covet wealth bring disaster upon themselves").

"夫增高者志崩，贪富者致患" ("Those who pile up height court collapse; those who covet wealth bring disaster"). Chapter 48: "为学日益，为道日损" ("In the pursuit of learning, one gains daily; in the pursuit of the Tao, one loses daily").
Translation: What the ancients taught, I likewise teach to others.
Analysis: Wang Bi comments: "我之非强使人从之也，而用夫自然，举其至理，顺之必吉，违之必凶" ("I do not coerce others into following me; rather, I employ what is natural, setting forth the ultimate principle—those who accord with it will surely prosper, and those who oppose it will surely meet misfortune"). Laozi is not inventing new doctrines but transmitting the ultimate principles of the Way of Heaven. This sentence reflects Laozi's attitude toward the transmission of the Tao: truth is universal, shared between antiquity and the present.
Similar views: Wang Bi: "我之非强使人从之也，而用夫自然，举其至理" ("I do not coerce others into following me; rather, I employ what is natural and set forth the ultimate principle").
Translation: Those who rely on brute force and aggression do not die a natural death; I shall take this as the fundamental starting point of my teaching.
Analysis: The entire chapter concludes with this cautionary maxim: whoever relies on force and tyranny will inevitably come to a bad end. This is a concrete illustration of "diminished yet thereby increased, increased yet thereby diminished"—those who believe themselves strong (increase) end up destroyed (decrease). Laozi takes this as the foundational starting point of his teaching. Heshanggong comments: "强粱者，谓不信玄妙，背叛道德，不从经教，尚势任力也。不得其死者，为天命所绝，兵刃所伐" ("'The violent and overbearing' are those who do not believe in the mysterious and subtle, who betray the Tao and Virtue (德), who refuse to follow the teachings of the classics, and who revere power and rely on force. 'Not dying a natural death' means they are cut off by Heaven's mandate and struck down by blades").
Similar views: Heshanggong: "老子以强梁之人为教，诫之始也" ("Laozi takes the violent and overbearing as a teaching—this is the beginning of his admonition"). Wang Bi: "人相教为强梁，则必如我之教人不当为强梁也" ("If people teach one another to be violent and overbearing, then I must teach people that they should not be violent and overbearing").
Translation: The violent and overbearing do not die a natural death—I shall take this (as a cautionary counter-example) as the starting point of my teaching.
Analysis: Wang Bi's commentary offers a distinctive perspective: "得其违教之徒，适可以为教父也" ("Those who obtain such wayward disciples who defy the teaching may use them aptly as the 'father of teaching'")—the tragic fate of the violent and overbearing serves precisely as teaching material, using negative examples to instruct the world. "Teaching father" (教父) = "father of teaching material" = "the starting point of admonition." This interpretation places greater emphasis on pedagogical methodology: teaching through counter-examples.
Similar views: Wang Bi: "故得其违教之徒，适可以为教父也" ("Thus those who obtain such wayward disciples may use them aptly as the 'father of teaching'").

[Core Divergences]
Chapter 42 is the most important cosmogonic chapter in the Tao Te Ching. The sixteen characters "道生一，一生二，二生三，三生万物" (The Tao produces the One; the One produces the Two; the Two produces the Three; the Three produces the myriad things) sketch the complete process from the ultimate ontological ground to the proliferation of all things. Wang Bi and Heshanggong represent two fundamentally different interpretive paths: Heshanggong's cosmogonic Qi-transformation theory (primordial Qi → Yin and Yang → harmonizing Qi → myriad things) became the theoretical foundation for later Daoist cultivation practices; Wang Bi's theory of logical unfolding (Non-being → Being → distinction → multiplicity) became the core thesis of Wei-Jin Xuanxue (Dark Learning). Each interpretation has its merits—the former is concrete and practically applicable, while the latter is abstract yet profound.
