Complete Guide to Zi Wei Dou Shu Grade B Stars: How Hongluan, Tianxi, and Other Auxiliary Stars Shape Your Chart
In a Zi Wei Dou Shu (紫微斗数) birth chart, beyond the 14 major stars (Zi Wei, Tian Ji, etc.), there are numerous Grade B stars that act as "assistants" or "seasoning" to the major stars, adding rich detail to the chart. Grade B stars include auspicious ones like Hongluan (Red Phoenix), Tianxi (Heavenly Joy), Longchi (Dragon Pool), and Fengge (Phoenix Pavilion), as well as inauspicious ones like Tianku (Heavenly Cry), Tianxu (Heavenly Void), and Tiankong (Sky Void). Understanding these auxiliary stars allows you to interpret life's trajectory from a more multidimensional perspective. This article systematically outlines the core traits, classifications, and functions of Grade B stars, and teaches you how to integrate them with major stars for comprehensive judgment.

Classification and Basic Traits of Grade B Stars
Grade B stars are numerous and can be classified by nature into auspicious, inauspicious, and neutral stars. Auspicious stars include Hongluan, Tianxi, Longchi, Fengge, Tianchu (Heavenly Kitchen), Tianfu (Heavenly Blessing), Tianguan (Heavenly Official), Fenggao (Seal of Honor), Taifu (Platform Assistant), Bazuo (Eight Seats), Enguang (Grace Light), and Tiangui (Heavenly Nobility), which signify celebration, benefactors, talent, and reputation. Inauspicious stars such as Tianku, Tianxu, and Tiankong indicate sorrow, depletion, and solitude. Additionally, some stars like Santai (Three Terraces) and Bazuo appear in pairs, reinforcing specific areas.
Hongluan and Tianxi: True Love and Celebration
Hongluan and Tianxi are a fixed pair, collectively known as the "Luanxi Twin Stars." Hongluan belongs to Yin Water and governs true love, marriage, and charm; Tianxi belongs to Yang Water and governs celebration, popularity, and neutralizing misfortune. When these two stars appear in the Ming Palace (Life Palace) or the Fude Palace (Spouse Palace), they often indicate early marriage, a high-quality spouse, and frequent joyous events. They are most potent when in the Chou, Yin, Mao, Chen, Xu, and Hai palaces; when fallen, their power diminishes. Hongluan leans more toward romantic feelings, while Tianxi emphasizes social joy.

Longchi and Fengge: Talent and Reputation
Longchi and Fengge are the "Dragon and Phoenix Twin Stars." Longchi belongs to Yang Water and governs academic success, benefactors, and culinary fortune; Fengge belongs to Yang Earth and governs artistic talent, appearance, and female benefactors. When these two stars appear in the Ming Palace or the Guanlu Palace (Career Palace), they favor examinations, arts, and public service, enhancing social reputation. They are most potent in the Chen, Xu, Chou, and Wei palaces; when fallen, talent may be hard to display.
Tianchu: Culinary Fortune and Public Service
Tianchu belongs to Yin Earth and governs culinary fortune, salary, and cooking skills. When it enters the Ming Palace or Guanlu Palace, it indicates a life free from food and clothing worries, suitable for public service or the catering industry. When combined with Wuqu (Martial Arts) or Tianfu (Heavenly Treasury), it brings prosperous wealth and stable nobility.
Tianfu and Tianguan: Blessing and Noble Purity
Tianfu is the exclusive auxiliary star of Tian Tong (Heavenly Harmony), governing blessings, longevity, joy, and benefactor luck; Tianguan is the exclusive auxiliary star of Tian Liang (Heavenly Beam), governing noble purity, prominence, and reputation. These two stars respectively reinforce the blessing and noble qualities of their major stars, with Tianfu focusing more on comfort and enjoyment, and Tianguan emphasizing official dignity.
Fenggao and Taifu: Honor and Status
Fenggao is the exclusive auxiliary star of Youbi (Right Assistant), governing bestowal of titles and social prestige; Taifu is the exclusive auxiliary star of Zuofu (Left Assistant), governing status ladders and benefactor paving. When these two stars appear together, they reinforce the authority and honor of the major stars, favoring examinations, promotions, and official recognition.
Bazuo, Enguang, and Tiangui: Power and Benefactors
Bazuo belongs to Yin Earth and governs official seals, academic success, and stable status; Enguang belongs to Yang Fire and governs benefactor support and special opportunities; Tiangui belongs to Yang Earth and governs proximity to nobility, gaining favor, and establishing credibility through trust. These three stars are all benefactor stars; when they enter the Ming Palace or Guanlu Palace, they make it easy to gain appreciation from elders or superiors, leading to a smooth career.
Tianku and Tianxu: Sorrow and Depletion
Tianku belongs to Yang Fire and governs pessimism, internal depletion, mourning, and financial loss; Tianxu belongs to Yin Fire and governs emptiness, depletion, and mental anxiety. These two stars are a fixed pair, collectively known as the "Ku Xu Twin Stars." They are most potent in the Chou, Mao, and Shen palaces, where their inauspicious nature is greatly reduced; when fallen, they indicate weak relationships with relatives, financial loss, and depletion. When combined with Ju Men (Gate of Darkness), their inauspicious nature is strongest, easily leading to disputes and mourning.

Tiankong: Emptiness and Spirituality
Tiankong belongs to Yang Fire and governs emptiness, depletion, solitude, and spirituality. It acts like a "filter," reducing blessings when meeting auspicious stars and reducing harm when meeting inauspicious stars. When it enters the Ming Palace, the person is intelligent and sensitive, fond of metaphysics, but prone to daydreaming without grounding, and has shallow relationships with relatives. When combined with Tai Yang (Sun) or Tai Yin (Moon), it can turn inauspicious into auspicious, indicating clear thinking.
How Do Grade B Stars Interact with Major Stars?
The power of Grade B stars is often manifested through major stars. For example:
- Zi Wei + Hongluan/Tianxi: Noble and celebratory, marriage is dignified, spouse has social status.
- Tianfu + Longchi/Fengge: Wealthy and elegant, luxurious home, prominent reputation.
- Tian Tong + Tianfu: Blessings and longevity, a life of ease, constant benefactors.
- Tian Liang + Tianguan: Noble and pure, suitable for medical or education fields, excellent reputation.
- Ju Men + Tianku/Tianxu: Many disputes and gossip, prone to financial loss and mourning, need careful words and actions.
In practical interpretation, one must consider the brightness of major stars, the brightness or fall of Grade B stars, and the influence of the Four Transformations (Hua Lu, Hua Quan, Hua Ke, Hua Ji). For example, when Tianku is bright in the Chou palace, it may instead bring fame through artistic talent; when Tiankong is in the Fude Palace (Virtue Palace), although the person feels lonely inside, it is suitable for spiritual practice or creative work.
Common Misconceptions and Practical Advice
Misconception 1: Grade B stars are more important than major stars. In reality, major stars determine the basic pattern of the chart, while Grade B stars only provide auxiliary modifications. For example, if Zi Wei is in the Ming Palace with Tianku, the imperial aura of Zi Wei will greatly weaken the sorrow of Tianku, so it cannot be judged as purely inauspicious.
Misconception 2: Inauspicious stars are always bad. Inauspicious stars like Tianku and Tianxu, when bright or paired with auspicious stars, may instead stimulate artistic inspiration and enhance empathy, making them suitable for psychology or arts fields.
Practical advice: When learning Zi Wei Dou Shu, first master the 14 major stars, then gradually incorporate Grade B stars. You can use the Zi Wei Dou Shu chart tool to view your own chart, focusing on the positions of stars like Hongluan, Tianxi, Tianku, and Tianxu, and judge them in combination with major stars.

Frequently Asked Questions
How can Grade B stars be quickly located in a chart?
Grade B stars are usually distributed across the twelve palaces of the chart, either in the same palace as major stars or shining upon them. You can generate a chart with one click using professional charting software or the online tool, where star names are marked with their grade (e.g., Grade B). Pay special attention to stars like Hongluan, Tianxi, Tianku, and Tianxu, which have a greater impact on marriage and emotions.
Does the simultaneous appearance of Hongluan and Tianxi guarantee a happy marriage?
Not necessarily. When the Luanxi twin stars are bright in the Ming Palace or Fude Palace, they indeed indicate early marriage and a high-quality spouse, but the auspiciousness or inauspiciousness of the major stars must also be considered. For example, if the major star in the Fude Palace is Ju Men or Tuo Luo (Vexation), there may be disputes or twists in the relationship. Additionally, when the Luanxi stars are fallen, their power is weakened, requiring late marriage or experiencing adjustments.
Does Tianku and Tianxu in the Ming Palace mean a lifetime of misfortune?
Not absolutely. When Tianku and Tianxu are bright in the Chou, Mao, or Shen palaces, their inauspicious nature is greatly reduced. If they encounter auspicious stars like Lu Cun (Salary Storage) or Hua Lu (Transformation of Wealth), they may instead bring fame and abundance. For example, artists' charts often have Tianku, which stimulates their sensitivity and empathy. It is recommended to judge based on the overall number of auspicious stars and the Four Transformations in the entire chart.
