What's actually inside the letter.
Taiyi's weekly letter draws on systems most readers in the English-speaking world have heard of vaguely but rarely seen explained simply. Two plain-English starts.
Bazi in plain English: what the four pillars actually are
The Chinese system for reading a person from their birth date and time. No mysticism — a calendar-based five-element calculus you can follow on paper. What a "day master" is, why the same birthday in different cities gives different charts, and where the system is honest about what it can't say.
Qimen in plain English: a tactical calendar, not a horoscope
If bazi is your chart, qimen is the week. A 1,080-plate forecasting system used historically for timing decisions — when to ship a deal, which direction to face for a hard conversation, when to wait. What the eight doors and nine palaces mean, and why qimen is mostly about when, not who.
Why you hit the same wall every year, same month
If a rough patch keeps landing in the same month, year after year, it usually isn't coincidence. The calendar mechanic behind recurring "off" months — and what to actually do about it before it happens again.
The one question to ask before you sign anything big
People who use timing systems before big decisions aren't being superstitious — they're buying themselves a pause. Why "sleep on it" works, formalized into a centuries-old tactical calendar.
