I spent 16 hours playing Mahjong with friends. We started at 2pm and ended the session at 6am (we had a break for a short dinner only). This is a new record for me.
Another new record for me:
I was the second player and I could not believe my eyes when I saw my tiles - it was PERFECTLY arranged. After I drew my first tile, I won immediately - Ping Hu - Men Qing - Zi Mo!!!
None of us (with more than 40 years of collective mahjong experience) have seen anything like that before. You gotta be a mahjong player to appreciate the RARENESS of this win.
I might never see such a win again in my life.
That's how rare it is.
