He dug out sets of the classic Chinese tile game from his parents house and brought them to San Francisco, where he started hosting mahjong nights in his apartment.The gatherings became so popular that the 25-year-old Chinese American began hosting pop-up mahjong parties in restaurants, bars and nightclubs around San Francisco.Mahjong, invented in 19th century China, is gaining popularity with a new generation of players looking to get off their phones and socialize in the real world. Lees Youth Luck Leisure (YLL) Mahjong Club now hosts bimonthly parties with up to 30 tables and 200 guests. They attract a diverse, young crowd drawn to the festive atmosphere, live DJs, custom cocktails and chance to meet new friends. Instructors are on hand to teach novices. A lot of people are just really intrigued even though they dont really know how to play, Lee said. Theres a cultural component theyre trying to connect with. Its kind of like a cultural nostalgia.Eventbrite reports there was a 179% increase in U.S. mahjong events on its platform from 2023 to 2024. Theres been a 179% increase in mahjong events in the U.S. from 2023 to 2024, according to Eventbrite, a popular ticketing app. The event platform says Gen Z is also showing a growing interest in other grannycore activities such as baking workshops and needlework circles that happen offline. In mahjong, four players draw and discard tiles with different suits, numbers and Chinese characters. The object is to build a winning hand of four sets of three and one pair.Its a really tactile game, and its really a social game. It really easily builds community among people, said Nicole Wong, a writer and audio producer in Oakland. Its a good way to unplug and not just be on your phone. Wong learned how to play when she visited her Chinese grandparents in New Zealand in 2009. Several years ago she found her parents mahjong table and game sets, and started hosting mahjong nights with her friends.In 2019, she launched The Mahjong Project, an instructional guide and oral history project inspired by her familys love of the game. That led her to publish Mahjong: House Rules from Across the Asian Diaspora, an illustrated book that explores the games history, strategies, traditions and styles of play. For the Asian American community, I think theres interest in connecting to your heritage and your culture in a way that was not the case when I was growing up, Wong said.YLL Mahjong Club has held nearly 20 events in San Francisco since it started last year. Lee said its an opportunity to introduce people to the game as well as bring business to local restaurants, bars and food vendors. Lees sister started hosting similar events in Los Angeles. There are plans to expand to other U.S. cities.The demand is rising, said Lee, a management consultant in business school. Its not just an interest to learn how to play mahjong, but to find a third space or another community to do things with. Joyce Yam, YLL Mahjong Clubs sponsorship manager, helps manage the San Francisco events, which sell out fast and have long waiting lists.We welcome people who have no experience at mahjong at all, and we have TAs who teach the people how to play the game. And they love it so much that they keep coming back, Yam said.Ethan Vuong, a Florida native who lives in San Francisco, started playing with friends a couple years ago. He saw it as a way to connect with his Chinese heritage and make new friends. Hes a regular at Oaklands Baba House and YLL Mahjong Club events, where he volunteers to teach newcomers.Its not just a skill or mechanics-based game, its an expression of your personality, Vuong said. I just keep playing because I have this goal that Im going to beat my grandma one day.
