Auspicious Numbers 吉數 — a phone number read by 梅花易數
A number you carry every day can be cast as a hexagram. The digits split into two halves, each half's sum becomes a 先天八卦數 trigram, and the total picks the moving line. The trigram without the moving line is 體 — you. The other is 用 — the number itself. What passes between them says whether the number supports its owner or works against them.
How Tian Qi reads a number
The cast is 梅花易數, not a digit-pair chart. It names 體 and 用 explicitly rather than assuming the upper trigram is always 體 — a rule settled against the classical cases — and derives the changed hexagram from the moving line the same cast produced. The score is built on 體用生剋 across the primary, changed and nuclear hexagrams, weighted the way the source texts weight them.
What you get
A free preview shows both trigrams, your hexagram and its Pythagorean root. The full analysis adds the score, the 體用 verdict in plain English, the changed and nuclear hexagrams, and a written reading. You can also generate a number that lands on an auspicious hexagram, keeping a country prefix, locked digits and any digits you want to avoid.
