About the 3 checks
KZEN checks three classical methods: Kim Lâu, Hoang Ốc, and Tam Tai.
Avoid personal-family limits
Based on lunar age and traditionally tied to family wellbeing.
Formula: (lunar age – 10) ÷ 9 — remainder 1, 3, 6, or 8 means Kim Lâu applies.
Avoid house-fortune limits
Six palaces rotate by construction age to determine auspiciousness.
Six palaces: Nhất Cát · Nhị Nghi · Tam Địa Sát · Tứ Tấn Tài · Ngũ Thọ Tử · Lục Hoang Ốc.
Avoid three-year hardship cycles
Each zodiac group has three inauspicious years in a 12-year cycle.
Cycles follow Thân-Tý-Thìn, Dần-Ngọ-Tuất, Tỵ-Dậu-Sửu, and Hợi-Mão-Mùi zodiac groupings.
