American expatriate Joseph Park Babcock, who is known for bringing Mah-Jongg to the United States, developed a love for the original game while working for the Standard Oil Company in Suzhou, Jiangsu Province. By the early 1920s, he created a version with simplified rules and began exporting Mah-Jongg sets – setting off a craze back home. The Pung Wo Co., also known as the Mei Ren Company, was another major exporter of the game.
