Before using AI to read feng shui, verify these three things first: in 2026 the Five Yellow is in the due south

Before using a chat AI to read feng shui, verify three things first: in 2026 the Five Yellow is in the due south and the Two Black is in the northwest; the Five Yellow is the disaster sha and the Two Black is the illness talisman, and the two cannot be used interchangeably; the compass bearing of the main door must be measured standing inside the door and facing out, since measuring while facing into the house will be off by 180 degrees. If any one of the three is wrong, the directional advice the AI gives must be checked again.

Recently quite a few tutorials have been circulating online, teaching people to hand a floor plan, the main door bearing and their troubles in life to a chat AI, then question it step by step according to instructions. The method itself is not bad: first state clearly what you want to solve, then give the spatial data, and finally measure the direction. The order is right.

The real risk lies in the chart. A chat AI has no built-in flying star calculation; the directions it gives are generalised from large amounts of text. When the year changes and different schools disagree, it can state something wrong very fluently, and very confidently.

So before moving furniture or buying ornaments according to its advice, it is worth spending five minutes checking the three things below.

The annual flying stars change the star in the central palace once a year. After the Beginning of Spring in the 2026 bing-wu year, the star entering the central palace is One White, and it then flies in order according to the Lo Shu sequence: One White in the centre, Two Black in the northwest, Three Jade in the due west, Four Green in the northeast, Five Yellow in the due south, Six White in the due north, Seven Red in the southwest, Eight White in the due east, Nine Purple in the southeast.

In other words, in 2026 the Five Yellow disaster star is in the due south, the Two Black illness star is in the northwest, and the annual literary star Four Green is in the northeast.

Some guides put this year Five Yellow in the due north. When the Five Yellow flies to the due north, that is a year with Nine Purple in the central palace, namely 2027. Off by one year, and the direction is off by half a house.

Another common confusion is calling the Five Yellow the illness star. The Five Yellow is the disaster star, governing accidents and misfortune, and should be kept still rather than disturbed; the Two Black is the illness star, governing the health of the household. The two are remedied in a similar direction, both using metal to drain earth, but their positions differ, and so do the priorities.

If a set of advice points the illness position at where the Five Yellow sits, the result of following it is that the real Two Black position is left unaddressed.

All directions are derived from the facing of the main door. The correct way to measure is to stand inside the main door, with your back to the interior and facing out through the door, hold the phone flat with its top pointing out through the door, and read the bearing; standing at the centre of the home facing the main door gives the same direction.

The most common mistake is measuring while facing into the home, which comes out exactly 180 degrees off. Once the facing is reversed, the view outside the window, the fortunes of the nine palaces and the location of the wealth position all fall on the opposite side.

There is a simple way to check: if the window opposite faces the main door directly, the window orientation should differ from the main door by about 180 degrees. After measuring, stand at the window and take a look; whether the direction is right is clear at a glance. If the main door and the window are not on the same axis, this relationship does not hold, and you can instead take readings at two or three positions inside the house and compare them against each other.

Chat AI is good at explaining concepts, such as why a through-passage sha makes people feel that qi does not gather, or why the bed head should rest against a solid wall. Treating it as an introductory book that answers questions is an appropriate use.

What it cannot do is see your actual space. A floor plan has no dimensions, so it does not know whether two doors are one and a half metres apart or five metres; it cannot see out of the window, so it does not know whether the corner of the building opposite points straight at your window, nor whether there is a hospital or a graveyard three hundred metres away. These judgements need actual data.

This is especially true of the external environment. Sky slash, sharp corners and oppressive pressure depend on the height and distance of the surrounding buildings, and on which floor you live on; in the same building, a sha that is blocked on a low floor may be completely invisible from a high floor, and the reverse is equally true.

The approach at 玄居 KarmaSpace is to hand the parts that require seeing over to measurement: a phone scan yields the room actual dimensions and furniture positions, and the nine palaces are divided according to true north rather than the up and down of a floor plan; the environment outside the windows is calculated from government building height data and map data, judging window by window what can be seen.

The annual flying stars are computed by program, not by inference; the days for placing remedies are chosen according to the almanac, avoiding broken days and days that clash with the zodiac sign of the household head. What AI does here is explain these results in language people can understand.

One, see whether the advice puts the 2026 Five Yellow in the due south and the Two Black in the northwest. If not, the whole set of directional advice should be questioned.

Two, measure the main door bearing again, confirm that it was measured facing out through the door, and then check it against the direction of a window.

Three, for any judgement involving what is outside a window, such as whether there is a sharp corner or a gap opposite, go to the window and look for yourself, or confirm it with a tool that uses actual data; do not rely on a written description alone.
