Each day has its own earthly branch, one of the twelve zodiac animals. That day branch has three harmonious animals: its Six Harmony (六合) partner and its two Three Harmony (三合) partners. Of those three, the wallpaper takes the first one that also harmonizes with your own day animal, the branch of the day you were born (not your birth year). If none of them does, it takes the first one that does not clash with your day animal. The animal is a small figure inside the scene, under five percent of the picture, seen from behind or in silhouette, and the dragon always flies across the sky.
The colors and the landscape come from the element your chart needs most, worked out by the same engine as your Saju reading. Each element has its own landscape, and the line under your wallpaper names it:
- Wood: A forest in the colors of Wood, the element you need
- Fire: A sunlit meadow in the colors of Fire, the element you need
- Earth: Mountains and plains in the colors of Earth, the element you need
- Metal: A rocky valley in the colors of Metal, the element you need
- Water: A lakeside in the colors of Water, the element you need
The season is the real one where you are, read from your device's time zone. In the northern hemisphere the seasons turn at the solar terms. For 2026 the dates are: spring February 4, summer May 5, autumn August 7 and winter November 7. Temperate southern time zones, such as Australia, New Zealand, Argentina, Chile and South Africa, get the opposite season. Tropical time zones follow the northern calendar.
The scene is one moment of a short story. It depends on how many of your three current periods, your ten-year period, this year and this month, carry the element your chart needs or the element that backs it up. Before your first ten-year period begins, only the year and the month are counted.
- None: resting beside a lantern under the eaves
- One: dawn breaking over still water
- Two: setting out across an old stone bridge
- Three: arriving at a stone gate before a wide horizon
Every picture is drawn for the shape of a screen: tall phones, phones, tablets, computer monitors and ultrawide monitors. You can register up to 3 devices, and each gets its own picture cut to its exact resolution. On phones and tablets the top third stays open sky, so the lock-screen clock is easy to read. A dimmed version is made for the home screen so icon labels stay readable. You choose the art style, and each device gets its own picture fitted to its screen. Your fortune changes every day, so the picture does too.
The picture never contains letters, numbers, signatures, seals, calligraphy, people, faces, talismans or religious symbols. Each new picture goes through an automatic vision check for text, seals, people, symbols, distortion and the right animal.
Only the ingredients above (style, animal, colors and landscape, season, scene and screen shape) are sent to the AI image model. Your name and birth date are never sent. People who share the same ingredients share the same set of pictures.
