A Triple Number (AAA) is a number like 888 / 666 / 999. In Chinese number culture it means ultimate luck, strongest aura — one of the classic "lucky number" types.
Value depends on: the digits (8, 9, 6 are prized; 4 lowers value), rarity (more repeats / cleaner pattern = pricier), and the carrier prefix. An 8-heavy Triple Number (AAA) fetches the most.
Meaning "ultimate luck, strongest aura". But a number type alone doesn't decide if it lifts or drains you — your full number's hexagram does.
