Mah Jong A Jewish Tradition?

Why is this Chinese game an American Jewish tradition? It just so happens that in the 1920's there was a popular song, "Since Ma is Playing Mah Jong" by Eddie Cantor (who was Jewish), but it was in the 30's when it became very popular game among Jewish women. Jewish women founded the National Mah Jongg League in 1937, and published the first American mahjong rulebook, Maajh: The American Version of the Ancient Chinese Game. This organization still publishes the yearly card of winning hands and official rules. But Mah Jong is still a Chinese game and popular in many countries with different variations.

Our new tradition at Mah Jong is to take a photo if a player wins a difficult hand! or if it is their first Mah Jong win!
