One square per year, one row per 大運. The colour is the rules' score: the 大運 character in force (干 for its first five years, 支 for the last five) ±1, the 流年 干 and 支 ±½ each, a 三合/三會 completed ±1, a 天干合化 ±½, and 沖/絕/害/破 on a 喜 or 忌 natal branch up to ±1. It cannot see 做功 or 破局. Tap a year for the full rule reading, split into 財運 money, 事業 career, 感情 love and 健康 health. Rate the years you have lived, area by area (a year can be good for money and bad for health), add a note if you like, and the strip shows where the rules and your life disagree — those are the years to study.
