TL;DR: Ân Quang and Thiên Quý are a pair of auspicious stars placed according to the birth day, but the starting point for counting is the two hour stars: Ân Quang takes the Văn Xương palace as the first day, counts forward to the birth day then moves back one palace; Thiên Quý takes the Văn Khúc palace as the first day, counts backward to the birth day then moves back one palace. This method of placing Thiên Quý is the Vietnamese book approach used by the Nhật Nguyệt utility, making Ân Quang and Thiên Quý symmetrical across the Sửu Mùi axis; Chinese books and the translated Đẩu số tinh thành instead count forward from Văn Khúc, so the Thiên Quý palace differs and the two stars are no longer symmetrical. Because they depend on both birth hour and birth day, the two stars can only be placed after Xương Khúc have been placed. Books group them among auspicious and benevolent stars, governing favors and support, often read together with Tam Thai and Bát Tọa as a noble person star set.
How Are Ân Quang and Thiên Quý Placed, and Why Are They Called the Noble Stars?
What Are Ân Quang and Thiên Quý in Tử Vi?
Ân Quang and Thiên Quý are two auxiliary stars in the auspicious star group, also called fortune stars or benevolent stars, governing good luck, kindness and support. In the common understanding, Ân Quang is the star symbolising good fortune and compassion, while Thiên Quý is described as a fortune star carrying a gentle energy, governing blessings, protection and help from benefactors. The two are usually mentioned as a pair, because their placement is tightly bound together through the two stars Văn Xương and Văn Khúc.
What is worth noting is that these two stars are not placed by birth year or birth month, but by birth day and birth hour. This is what sets them apart from most other stars in a chart, and it is also why many people who look them up find that their Ân Quang and Thiên Quý positions are not where they expected.
Why Are Ân Quang and Thiên Quý Called the Noble Stars?
The name "noble stars" comes from the meaning of the characters: Ân is grace, a debt of kindness; Quang is light, illumination; Quý is noble, worthy of respect. Put together, this pair of stars is understood as the light of grace and noble dignity, that is, the image of a person guided and supported by heaven above or by people in life.
According to the book Đẩu số tinh thành, in the section discussing the order of placing stars, Ân Quang and Thiên Quý are grouped with Tam Thai and Bát Tọa among the stars placed by day. Tam Thai's placement takes Tả Phụ as its marker, Bát Tọa takes Hữu Bật as its marker, counting to the birth day. These four stars are often read together as one set, called the benefactor set, or in some documents called the Tứ Vinh set when combined with Thai Phụ and Phong Cáo.
In the common understanding within the Tử Vi tradition, Thiên Quý "governs blessings, nobility, honour, protection and help from benefactors", while Ân Quang "governs good fortune, protection, and blessing for its owner". This way of speaking is traditional and symbolic, not a specific promise about some particular helper in real life.
Detailed Placement of Ân Quang and Thiên Quý
Both stars use the lunar birth day as the count, and take the palace of an hour star as the starting point. The key is that Văn Xương and Văn Khúc must be placed first, because these two stars depend on the birth hour.
Placing Ân Quang
Take the palace containing Văn Xương as the first day, count clockwise to the birth day, then step back one palace. The palace where you stop is the position of Ân Quang.
Placing Thiên Quý
Following the Vietnamese book method used by Nhật Nguyệt's chart-casting tool: take the palace containing Văn Khúc as the first day, count counter-clockwise to the birth day, then step back one palace (back relative to the direction just counted, that is, forward one palace clockwise). The palace where you stop is the position of Thiên Quý. The verse "Khúc kia hãy dùng, nghịch về ngày đẻ, một cung lui về" describes exactly this method. By this method, Ân Quang and Thiên Quý are symmetrical across the Sửu Mùi axis. Three charts printed in Số Tử Vi Kinh Nghiệm (Quan Xuân Thịnh) match this method.
Chinese books and the translation of Đẩu số tinh thành (pp. 30, 39) instead count clockwise from Văn Khúc just like Ân Quang, so the Thiên Quý palace by that method differs from the table at the end of this article, and the two stars are no longer symmetrical.
Why Xương and Khúc Must Be Placed First
Văn Xương and Văn Khúc are two stars placed by birth hour. Văn Khúc starts at the Thìn palace, counting clockwise to the birth hour. Văn Xương starts at the Tuất palace, counting counter-clockwise to the birth hour. Since Ân Quang and Thiên Quý take the palaces of these two stars as their first day, Quang Quý cannot be placed until Xương and Khúc are placed. This is why, in the order of casting a chart, Quang Quý always comes after Xương Khúc.
Table of Ân Quang and Thiên Quý Positions by Birth Hour and Birth Day
The table at the end of the article is calculated by exactly the placement method used by Nhật Nguyệt's Tử Vi chart-casting tool, following the Vietnamese book method: Thiên Quý counts counter-clockwise from Văn Khúc. Chinese books count clockwise, so the Thiên Quý column according to Chinese books will differ. Birth days 12 days apart fall in the same palace. You can see the full table at the end of the article.
Where the Sources Disagree on the "Step Back One Palace"
There are two main methods, and learners need to check against a concrete example before trusting either reading.
The first method, following Vietnamese books and Nhật Nguyệt's tool: after counting to the birth day, step back one palace relative to the direction just counted. For Ân Quang, since the count is clockwise, stepping back one palace means going counter-clockwise. For Thiên Quý, since the count is counter-clockwise, stepping back one palace means going clockwise. This method gives Ân Quang and Thiên Quý symmetry across the Sửu Mùi axis, and matches the three charts printed in Số Tử Vi Kinh Nghiệm (Quan Xuân Thịnh).
The second method, following Chinese books and the translation of Đẩu số tinh thành (pp. 30, 39): Thiên Quý also counts clockwise from Văn Khúc just like Ân Quang, then steps back one palace in the opposite direction. This method gives a Thiên Quý palace different from the table at the end of the article, and the two stars are no longer symmetrical across the Sửu Mùi axis.
A point to note: if you only read a short description, it is very easy to confuse "step back one palace" with "skip the birth-day palace". These two are actually the same, but the different wording makes it easy for beginners to miscount by one palace. The safest way to check is to take a chart whose Quang Quý positions are already known, then try counting by both methods to see which one matches.
How Are Ân Quang and Thiên Quý Read Together with Tam Thai and Bát Tọa?
Tam Thai and Bát Tọa are two stars also placed by birth day, but their starting markers are Tả Phụ and Hữu Bật. According to Đẩu số tinh thành, Tam Thai takes the Tả Phụ palace as the first day, counting clockwise to the birth day, while Bát Tọa takes the Hữu Bật palace as the first day, counting counter-clockwise to the birth day. Neither has the step-back-one-palace step that Quang Quý has.
When these four stars come together, books often call it the benefactor set, governing support, honour and being respected by others. In the traditional view, when Thiên Quý shares a palace with auspicious stars such as Ân Quang, Tả Phù, Hữu Bật and Thiên Quan, careers become smoother and benefactors lend support. This is a set-based reading, not an assertion that a single star can decide a person's fate.
Is Quang Quý an External Benefactor or One's Own Virtue?
This is where schools and books often disagree, and learners should know both readings.
The first reading, in the "external benefactor" direction: Quang Quý governs help from other people, from superiors, from people with power, or from some invisible force. In the common understanding within the Tử Vi tradition, Thiên Quý means "being helped by benefactors", "meeting people who support and accompany you through challenges".
The second reading, in the "one's own virtue" direction: Quang Quý is the inner quality of the chart's owner, kindness, integrity, and a sense of the debt of gratitude. Đẩu số tinh thành, when discussing Quang Quý, says they are "messengers" and "patrons", helping talent be recognised and learning be advanced. This reading emphasises inner strength rather than outer strength.
Some documents further distinguish: Tam Thai and Bát Tọa face outward, that is, they lean toward social relations, while Quang Quý shine inward, that is, they lean toward qualities and spiritual life. Not every book records this distinction, and it does not mean the two pairs of stars exclude each other. In practice, readers usually read both directions: Quang Quý is both what you have and what you receive from others.
The Level of "Rescue" That Books Assign to Quang Quý
Đẩu số tinh thành ranks Ân Quang and Thiên Quý in the group of "rescue stars of medium calibre", meaning they can reduce the negative impact of bad stars, but are not the strongest rescue stars. When meeting malefic stars, the presence of Quang Quý can help lessen the degree of misfortune and open a chance to get through difficulty.
In the common understanding among Tử Vi practitioners, Ân Quang is a star that "turns ill into good when meeting it", "has no weakened position, and brings good fortune in whatever palace it sits". This way of speaking is stronger than the wording of Đẩu số tinh thành. Readers should understand these as two different levels within the same tradition: one side says Quang Quý are good stars, rarely bad; one side says Quang Quý are medium-level rescue stars, with limits.
Whichever way you take it, Quang Quý should not be understood as absolute insurance. One good star cannot erase the impact of an entire combination of bad stars, and one pair of benefactor stars does not guarantee that a particular person will meet someone to help them in real life. This point needs to be stated clearly to avoid false expectations.
What Happens When Quang Quý Meets Hồng Loan and Đào Hoa?
Some documents note that Quang Quý can somewhat restrain the nature of Hồng Loan and Đào Hoa. This wording appears in articles about Hồng Loan and Thiên Hỉ, with the idea that Ân Quang and Thiên Quý govern intelligence and kindness, and so can soften somewhat the influence of stars leaning toward emotion and desire.
Note: this is a combined-star reading, not a hard rule. Not every book records this effect, and the degree of influence also depends on the whole chart. Learners should not take this one sentence to reach a firm conclusion about a specific chart.
A Few Points to Note When Reading Quang Quý
First, the position of Quang Quý depends on both birth hour and birth day, so two people born on the same day but at different hours can have Quang Quý in different palaces. This is why Quang Quý cannot be looked up by birth day alone.
Second, Quang Quý are not the dominant stars. They are auxiliary stars, and their effect depends on the main star and other auxiliary stars in the palace. A palace with Quang Quý but a weak main star can still meet many difficulties.
Third, the name "noble stars" is a symbolic name. It describes a tendency, a quality, a capacity to be supported, not a promise. Quang Quý should not be read as a guarantee that a person with this star will always be helped, nor as a sentence that a person without it will never meet a benefactor.
Fourth, when looking things up, the position of Quang Quý should be checked against at least two sources, because as noted, the "step back one palace" step has two interpretations and easily leads to being off by one palace.
Which Palaces Do Ân Quang and Thiên Quý Sit in by Birth Hour and Birth Day?
The two tables below are calculated by exactly the placement method used by Nhật Nguyệt's Tử Vi chart-casting tool, following the Vietnamese book method: Thiên Quý counts counter-clockwise from Văn Khúc. Chinese books count clockwise, so the Thiên Quý column according to Chinese books will differ. Birth days 12 days apart fall in the same palace.
| Star | Chinese character | Placement |
|---|---|---|
| Ân Quang | 恩光 | Take the Văn Xương palace as the first day, count clockwise to the birth day, then step back one palace. |
| Thiên Quý | 天贵 | Take the Văn Khúc palace as the first day, count counter-clockwise to the birth day, then step back one palace (Vietnamese book method; Chinese books count clockwise). |
