Wenwanggua

Wenwanggua is a astronomy topic covered in the lgStudy science library. This page brings together a partial reference excerpt, illustrations, worked examples, real-world applications and a short study plan, so you can understand Wenwanggua rather than just read about it. In short: Wen Wang Gua (Chinese: 文王卦; pinyin: Wén Wáng Guà) is a method of interpreting the results of I Ching divination that was first described in writing by Jing Fang in Han dynasty China. It is based on correlating trigrams to the Celestial Stems and Earthly Branches of the Chinese calendar, and then using the stem and branch elements to interpret the lines of the trigrams and hexagrams of the I Ching.

Key takeaways

  • Wenwanggua belongs to astronomy; place it in that map before memorising details.
  • Learn the definition first, then one example that makes the definition concrete.
  • Connect Wenwanggua to a quantity you can measure, compute or draw — that is where exam questions come from.
  • Reproduce the core statement of Wenwanggua from memory before moving on to harder problems.

Reference excerpt

Wen Wang Gua (Chinese: 文王卦; pinyin: Wén Wáng Guà) is a method of interpreting the results of I Ching divination that was first described in writing by Jing Fang in Han dynasty China. It is based on correlating trigrams to the Celestial Stems and Earthly Branches of the Chinese calendar, and then using the stem and branch elements to interpret the lines of the trigrams and hexagrams of the I Ching. The method is popular in South East Asia. It is known by various names: (Liu Yao) (six lines divination) refers to the fact that it interprets the meaning of six symbols; the Najia method, indicates its logic of elemental values derived from the Chinese calendar; Huo Zhu Lin (火珠林), or the Fire Pearl Forest method, refers to a classical textual tradition associated with this form of divination; Wu Xing Yi (changes of the five elements); or Wen Wang Ke (Lessons of King Wen). Despite being the mainstream method of practical I Ching divination in China, Wen Wang Gua and the Na Jia system were largely absent from major English-language translations of the I Ching throughout the twentieth century. Richard Wilhelm, in his appendix on the coin oracle, acknowledged the existence of this system, noting that there is "yet another kind of coin oracle, employing, besides the hexagrams of the I Ching, the 'five stages of change,' the cyclic signs, etc." He described it as a practice "used by Chinese soothsayers" and characterized it as a perpetuation of the ancient tortoise oracle that was "gradually supplanted by the I Ching." This characterization is not consistent with the system's continued and widespread use in Chinese divinatory practice.

History The name Wen Wang Gua means "King Wen's fortune telling hexagrams" (or trigrams, since gua can mean either hexagram or trigram). King Wen of Zhou and his son are traditionally said to be the authors of the I Ching. The elemental correspondences of the trigrams were not originally part of the tradition associated with King Wens name, but may have been based on a trigram sequence described in the Eighth Wing (one of the Ten Wings, a series of appendixes to the I Ching which are usually ascribed to Confucius). That the use of element correlation theories was relevant at the time can be seen from the extant records, such as the Luxuriant Dew of the Spring and Autumn Annals, a compilation of earlier texts which was attributed to Dong Zhongshu. As one modern researcher remarks: "Dong Zhongshu is generally remembered as the author of a detailed system of correspondences in which everything was correlated to one of the five fundamental forces, so that everything could be shown to be interrelated in an orderly and comprehensible manner." Jing Fang and his teacher, the author of the "Forest of Changes by Jiao", were among the first to apply this form of correlative thinking to I Ching divination.

Trigram values This is the text from section 5 of the Eighth Wing, an appendix to the I Ching, which relates the trigrams to the seasons of the year, and indirectly to the elements:

God comes forth in Kan (to His producing work); He brings (His processes) into full and equal action in Sun; they are manifested to one another in Li; the greatest service is done for Him in Khwan; He rejoices in Tui; He struggles in Khien; He is comforted and enters into rest in Khan; and He completes (the work of the year) in Kǎn. Kan and Sun (☳ and ☴) correlate with wood, the first of the elements in the Chinese calendar, then Li (☲) with fire, Khwan (☷) with earth, Tui and Khien (☱ and ☰) with metal, and Khan (☵) with water. Thus the elements appear in their generating sequence, which correlates with the seasons of the year and the trigrams. The Kăn trigram (☶), correlating with earth, has been placed at the end of the sequence because in it is said that God has completed His work, and this must appear to us at the end, even if from the point of view His relation with creation the work was actually complete after Khwan, after the greatest service is done for Him and before He does His own rejoicing and struggling. Section 2 of the Eighth Wing relates line positions top, middle and bottom to Heaven, Man and Earth respectively. Although traditionally attributed to Fu Xi, Shao Yong's binary or lexicographical order first appears in the eleventh century AD:

Jing Fang Larry James Schulz writes in his dissertation Lai Chih-Te, (1525-1604) and the phenomenology of the “Classic of Change” (Yìjīng):

"Jīng Fáng’s is the name associated with the earliest appearance of numerous other explanatory and integrative devices, among them the systematic application of a hexagram’s “nuclear trigrams (hùtǐ 互體 or zhōngyáo 中爻)” – lines two through four and three through five separately considered – to expound the hexagram’s verbal properties; the “Eight Palaces (bā gōng 八宮)” system of arranging hexagrams (...); and incorporation of the Five Phases (wǔxíng 五行), the “heavenly stems (tiāngān 天干)”, and the “earthly branches (dìzhī 地支)” designations to amplify the Change’s linear figures in what is called the “nàjiǎ 納甲” theory." More about this system can be found in Fung Yu-lan’s A History of Chinese Philosophy, Volume II.

Line values Jing Fang assigns stem and branch elements to the lines of the trigrams (the trigrams as a whole already had their own element correspondences). The correspondences of the trigrams for the Celestial stems and Earthly Branches below indicate the elements for each line of the trigrams, as opposed to the trigrams as a whole. Recent English-language discussion of Wen Wang Gua translation methodology has emphasized that its technical terms, charting structure, stems and branches, and case reasoning function as parts of a systematic divination framework rather than ordinary vocabulary.

Worked examples

Example 1 — a first encounter with Wenwanggua

Start with the simplest possible case. Write down what Wenwanggua claims or describes in one sentence, then invent the smallest concrete situation in which that sentence is true. In astronomy, the smallest case is usually a single object, a single equation or a single measurement. Check that every symbol or term in your sentence has a meaning in that case.

Example 2 — changing one variable

Take the situation from Example 1 and change exactly one quantity: double it, halve it, or set it to zero. Predict what should happen to Wenwanggua before you calculate. Comparing your prediction with the result is the fastest way to find out whether you understand the idea or only the words.

Example 3 — an exam-style question

Typical questions about Wenwanggua ask you to (a) state it precisely, (b) apply it to given data, and (c) explain a limitation. Practise writing all three answers in under five minutes; the third part is what separates a full-mark answer from an average one.

Applications of Wenwanggua

In research
Wenwanggua appears in astronomy research whenever the underlying quantities have to be modelled precisely. Papers usually cite it as a starting assumption and then explore where it breaks down.
In technology and industry
Engineering practice reuses Wenwanggua in design rules, simulations and safety margins. Knowing the idea lets you read a specification sheet and understand why the numbers look the way they do.
In the classroom
Wenwanggua is common in secondary-school and first-year university syllabi. It links to neighbouring topics Chinese mythology, Early scientific cosmologies, I Ching, so understanding it makes those chapters shorter.
In everyday life
Look for Wenwanggua outside the textbook — in sport, cooking, traffic, electronics or the sky above you. An example you found yourself is remembered far longer than one you were given.
