TaiSui (太歲) is the year’s presiding-deity star — one of the four classical annual sha but distinct from the others in character. Where the 5 Yellow, San Sha, and Year Breaker are unambiguously to-be-mitigated, TaiSui is to-be-respected. Classical reading: an authoritative elder who, when treated correctly, presides over the year’s favourable outcomes; when disturbed, withdraws that protection.
For 2028, TaiSui sits in 申 (Monkey), located in the Southwest sector. Treat the entire Southwest as TaiSui territory through 2028.
Classical rules are absolute: do not renovate the Southwest in 2028. No digging, no breaking ground, no major construction, no significant noise events. The seating rule is also classical — do not sit with your back to the Southwest for important meetings, contract signings, or significant household decisions.
For households where the head of household is born in a Monkey year, 2028 is the 本命年 (ben ming year) — classically a year of additional caution and traditional protective practice for those who follow it. The opposite branch (Tiger-born) faces the Year Breaker against their birth branch and has the most cautious year of the twelve.
