TL;DR: The single trigram Qian (☰) consists of three yang lines. It is the image of Heaven, belongs to the Metal phase in the five phases, and corresponds to the northwest direction according to the Later Heaven Eight Trigrams. The Shuogua calls Qian the father, the head, the horse, jade, metal, and says Qian is the trigram of the northwest. Nhật Nguyệt's suggestion: view Qian as a hint about clear and proactive beginnings, not as absolute advice for destiny or finances.
What is the Qian single trigram in the Bagua?
The Qian trigram (乾, ☰) is one of the eight single trigrams of the Bagua, made up of three yang lines stacked one on top of another without a break. In the system of trigram images, Qian is the image of Heaven, belongs to the Metal element in the five phases, and according to the Later Heaven Bagua corresponds to the Northwest direction. This is a pure yang trigram, tied to the image of the sky and to active energy.
What does the original text in the Shuogua say about the Qian trigram?
The Shuogua is one of the Ten Wings, traditionally attributed to Confucius; modern scholarship does not regard that attribution as proven. In this text, the Qian trigram appears in several chapters with the following passages (Chinese characters, Sino-Vietnamese reading and a close translation):
- 乾以君之 (Càn dĩ quân chi): Qian rules the myriad things through its virtue (chapter IV).
- 戰乎乾，乾，西北之卦也。言陰陽相薄也 (Chiến hồ Càn, Càn, tây bắc chi quái dã. Ngôn âm dương tương bạc dã): Qian is the trigram of the Northwest, speaking of yin and yang pressing against each other (chapter V)[1].
- 乾，健也 (Càn, kiện dã): Qian is strength, firmness (chapter VII).
- 乾為馬 (Càn vi mã): Qian is the horse (chapter VIII).
- 乾為首 (Càn vi thủ): Qian is the head (chapter IX).
- 乾，天也，故稱乎父 (Càn, thiên dã, cố xưng hồ phụ): Qian is Heaven, and so is called the father (chapter X)[1].
- 乾為天、為圜、為君、為父、為玉、為金、為寒、為冰、為大赤、為良馬、為老馬、為瘠馬、為駁馬、為木果 (Càn vi thiên, vi viên, vi quân, vi phụ, vi ngọc, vi kim, vi hàn, vi băng, vi đại xích, vi lương mã, vi lão mã, vi tích mã, vi bác mã, vi mộc quả): Qian is Heaven, is the circle, is the ruler, is the father, is jade, is metal, is cold, is ice, is deep red, is the good horse, is the old horse, is the lean horse, is the dappled horse, is the fruit on the tree (chapter XI).
How does Zhu Xi comment on the Qian trigram image?
In the Zhouyi benyi, in the section of the mnemonic verse for the images of the eight trigrams, Zhu Xi records a mnemonic for recognising the shapes of the eight single trigrams:
> 乾三連，坤六斷，震仰盂，艮覆碗，離中虛，坎中滿，兌上缺，巽下斷。
That is: Qian three lines connected, Kun six lines broken, Zhen like an upturned cup, Gen like an overturned bowl, Li empty in the middle, Kan full in the middle, Dui broken at the top, Xun broken at the bottom. This mnemonic helps learners remember the shape of the Qian trigram: three yang lines joined together without a break.
In Nhật Nguyệt's understanding
In Nhật Nguyệt's understanding, the Qian trigram evokes the image of an all-encompassing sky, ceaselessly in motion and a source of vital energy. Three yang lines joined together suggest continuity, without interruption, a state of pure yang before any interweaving of yin. In relation to Kun (Earth), Qian represents initiation, while Kun is reception and completion. This is Nhật Nguyệt's internal reading, not a statement of the Shuogua or of any particular commentator.
How does Qian relate to the other trigrams?
In the Bagua, Qian operates in relationship with the seven remaining trigrams. The most basic opposing pair is Qian and Kun (☷), symbolising Heaven and Earth, the two poles of yin and yang. When two single trigrams are stacked, they form doubled trigrams. Some doubled trigrams have Qian above or below:
| Doubled trigram | Hexagram number | Structure | Traditional meaning |
|---|---|---|---|
| Pure Qian | 1 | Qian above Qian | Six yang lines, symbolising ceaseless creativity |
| Tai | 11 | Kun above Qian | Heaven and Earth in harmony, a period of smooth flow |
| Pi | 12 | Qian above Kun | Heaven and Earth not communicating, a period of blockage |
| Da You | 14 | Li above Qian | Fire above Heaven, great clarity |
| Da Xu | 26 | Gen above Qian | Mountain above Heaven, great accumulation |
| Xiao Xu | 9 | Xun above Qian | Wind above Heaven, small accumulation |
| Xu | 5 | Kan above Qian | Water above Heaven, waiting |
| Da Zhuang | 34 | Zhen above Qian | Thunder above Heaven, great strength |
These doubled trigrams show that Qian can appear in either the upper or the lower position, depending on the hexagram, and each position carries its own meaning in the tradition.
A suggestion for today
Nhật Nguyệt's suggestion: if you are considering a new beginning at work, choose a moment when you are genuinely clear-headed and prepared, rather than acting only out of a fleeting sense of excitement. In matters of love, the spirit of Qian is clarity and initiative, but you still need to listen to the other person so as not to impose your own view. As for health, this is only a reference suggestion and does not replace medical advice; keep up regular movement and rest sensibly. As for home feng shui, according to the Later Heaven Bagua, Qian corresponds to the Northwest, so this area is often given attention when arranging a desk or a quiet space; this is a reference principle, not an absolute scientific rule.

What is the spirit of the Qian trigram in daily life?
The Qian trigram with its three unbroken yang lines is the symbol of Heaven, of initiation and ceaseless motion. Understanding Qian correctly does not stop at the shape of three lines but also includes its Northwest position according to the Later Heaven arrangement, its Metal element, and the images such as father, head, horse, jade and metal that the Shuogua listed. This is the foundation for approaching the doubled trigrams that contain Qian, as well as for applying it in feng shui and daily life in a spirit of reference, without absolutising it.
