How it's used
This term refers to a specific, high-scoring hand in Mahjong consisting only of ones and nines of all suits, plus honors. It is considered a very difficult hand to assemble, often requiring a great deal of luck and strategic discarding from opponents. Because it is so rare, it is usually assigned a very high point value in standard Hong Kong Mahjong rules.
Examples
You have been playing for so long, have you ever won with a Qing Yao Jiu?
He is very skilled this round, he actually self-drew a Qing Yao Jiu.

Common mistake
Learners often confuse this with 混么九, which allows for a mix of ones, nines, and honors, whereas 清么九 strictly requires the hand to be composed entirely of those specific tiles without any other numbers.
