noun
blessing of man; winning on a discard in the first turn
A mahjong yaku where a player wins by calling a discarded tile on their first draw, before they have had a chance to draw a tile themselves. Often considered a lucky hand.
from Chinese
親の第一ツモ前にロンすると人和が成立する。
If you call ron before the dealer's first draw, the blessing of man is completed.
人和は運が良くないと出ない役だ。
The blessing of man is a yaku that only appears when you're lucky.
From Chinese 人和 (rénhé), literally 'human harmony'. In mahjong, it refers to a win achieved through another player's discard.
