What each flag means
Their flirty years
The chart reads patterns, not choices. Two people with the same flags can live them in opposite ways, and nothing here says what anyone will do.
How the Red Flag Test works
The Red Flag Test is a red flag quiz with no questions to answer. It casts the bazi (birth chart) for one birthday, read as a man or a woman, and checks it against eight fixed rules drawn from the Chinese chart manuals: where the partner star sits, how much of it the chart carries, whether the marriage seat is clashed, whether the peach blossom sits in the chart, and four more. Each rule that fires is a red flag; every chart also gets green flags, and the years to watch.
The rules were measured on every birthday from 1950 to 2005, for men and for women. Without a birth time, about 24% of charts carry no red flag, 40% carry one, 25% two, 9% three and 3% four or more. A birth time adds the hour pillar and a little more to read, so the counts run slightly higher. Every flag on a result shows how many charts share it, from 1 in 4 down to fewer than 1 in 100.
What the classical texts actually warn about
The red flags in this test are not modern inventions. The Chinese chart manuals were written by men casting charts for marriages, and they are blunt about what worried them. The founding manual of the method, the Song-dynasty Yuanhai Ziping, has a chapter on wives and concubines, a chapter on a woman's chart, and a list of the stars that spell trouble at home. Five of its warnings are the backbone of the test.
The peers, and the partner they take
In bazi your own element appearing again in the chart is the peers, Companion and Rob Wealth (比劫), two of the ten gods. For a man, Wealth is also the wife, so a crowd of peers is read as rivals for her. The manual says it flatly: "a man who sees much Rob Wealth harms his wife; a woman who sees much Hurting Officer harms her husband," and in the chapter on wives it lists peers "splitting and seizing" among the signs of an unfaithful household. The test turns this into Friends come first: friends, rivals and the group chat get a vote.
The officer wounded
Hurting Officer (伤官) is the star of talent and talking back, read against your day master. On its own it is brilliance. Beside the Direct Officer, the star of rules and, in a woman's chart, the husband, it is the most quoted warning in the whole method: "when the officer star is seen, it is called the Hurting Officer meeting the officer, and a hundred kinds of calamity follow." The test reads it as Sharp tongue: the person who says the cutting thing, and is usually right.
Two partner stars at once
Every chart has a partner star, and it comes in two forms: the proper one and the restless one (for a woman, the Direct Officer and Seven Killings; for a man, Direct and Indirect Wealth). The Yuanhai Ziping gives a whole chapter to the case where both appear, titled "mixed officers and killings must be brought under control" (官杀混杂). The test calls it Keeps options open, and adds the sharper case where the restless form sits in the marriage seat itself: Falls for the thrill.
The peach blossom
The peach blossom (桃花) is the star the internet calls romance. Its own chapter in the Ming Sanming Tonghui calls it by two harsher names, the ruined god and the peach blossom curse, and closes: "Xianchi is not an auspicious star." Most charts only meet it in passing, once every twelve years. When it sits in the chart itself, the test flags Flirts without trying; when its year is coming, Flirty year. The branch relations page shows how it is placed.
A marriage seat under clash
The Sanming Tonghui assigns the family to the four pillars: "the year is the ancestors, the month the parents and siblings, the day the spouse and the self." The animal under your day master is the marriage seat. When another pillar clashes it (日支逢冲), the home is read as restless: close one month, distant the next. That is Hot and cold. The opposite, a pillar that combines with the seat, is one of the green flags: once committed, settled.
The eight red flags, and how rare each one is
Each flag is one fixed rule, applied the same way to every chart. The rates come from every birthday from 1950 to 2005, read for men and for women; a birth time adds the hour pillar, which gives most flags more places to appear. Most charts carry one or two red flags; about one in four carries none.
| Flag | The rule | Charts, no time | With a time |
|---|---|---|---|
| Attention magnet | The partner element fills 3 or more of the 5 characters around the day master (4 of 7 with a birth time), and the chart is heavy in it. | 5% | 4% |
| Falls for the thrill | The marriage seat holds the lover star (Indirect Wealth for a man, Seven Killings for a woman) instead of the spouse star. | 13% | 13% |
| Keeps options open | Both partner stars, the steady one and the restless one, appear in the chart. | 14% | 25% |
| Flirts without trying | The peach blossom branch sits in the chart itself, not just in a passing year. | 16% | 23% |
| Hot and cold | Another pillar clashes the marriage seat (the day branch). | 16% | 23% |
| Friends come first | The person’s own element, the peers, fills a third or more of the chart around them. | 27% | 23% |
| Sharp tongue | Hurting Officer appears twice, or on a stem beside the Direct Officer. | 13% | 22% |
| Flirty year | A peach blossom year falls in the next three years. | 25% | 25% |
What a chart can tell you, and what it cannot
A chart can tell you where the pressure sits: which kind of partner a person is drawn to, whether attention comes easily to them, whether home is a calm place or a busy one. It says this the same way for everyone born in the same hours, which is why the test is fair and why it is not a character reference. Two men with the same chart can be a faithful husband and a serial cheat. The manuals knew this; they read the chart as weather, and the person as the one deciding whether to go out in it.
A flag is also only half of a pairing. A sharp tongue next to a thick skin is a different marriage from a sharp tongue next to a sharper one, which is what the Love Compatibility Checker reads. For the warnings between two zodiac signs alone, see red flags by Chinese zodiac sign.
Questions people ask
What is a red flag test?
A red flag test is a short check for the warning signs in someone’s love life. Most of them are quizzes about behavior you have already seen. This one reads a birthday instead: it casts the birth chart (bazi) and checks it for the eight patterns the Chinese chart-reading manuals warn about in love, from the lover star in the marriage seat to the peach blossom. Every chart also gets its green flags.
Can I check someone else’s red flags?
Yes. Choose "Their chart", enter their birthday and whether to read the chart as a man or a woman. The birth time is optional; with it the chart has seven characters around the day master instead of five, so the reading is fuller. Nothing you enter is stored.
Is the red flag test accurate?
It is accurate to the chart: every flag is a fixed rule from the classical tables, applied the same way to every birthday, and each one shows how often it turns up across all charts. Whether a person lives out a pattern is another matter. A chart shows tendencies, not choices, and two people with the same flags can live them in opposite ways.
Does a red flag mean they will cheat?
No. No flag on this page says anyone will cheat, and none of them is a verdict on a person. "Falls for the thrill" means the marriage seat holds the lover star; "Keeps options open" means both partner stars appear. The old manuals read those as risks to manage, and plenty of faithful people carry both.
How many red flags is normal?
One or two. Measured on every birthday from 1950 to 2005, about 24% of charts carry no red flag, 40% carry one, 25% carry two, 9% carry three and 3% carry four or more (read without a birth time; with one, the counts run a little higher). Zero is rarer than one, and four or more is rarer still.
Why does it ask whether to read the chart as a man or a woman?
Because the partner star changes. In the Ziping method a man’s partner is the element his day master overcomes (Wealth), and a woman’s is the element that overcomes hers (Influence). The same birthday read both ways can flag differently.
What is a peach blossom year?
The year whose animal is your peach blossom branch, which is fixed by your day branch: Tiger, Horse and Dog days get the Rabbit; Snake, Rooster and Ox get the Horse; Monkey, Rat and Dragon get the Rooster; Pig, Rabbit and Goat get the Rat. It comes round once in twelve years and is read as a year of attention. The Ming manual that gives the rule adds that it is "not an auspicious star".
