Chicago was once a battleground for Chinese gangs

Chicago has a long history with organized crime. Its most famous - or infamous - mob boss was Al Capone. But it wasn't just Italian families that worked in Chicago's underworld. Decades ago, two rival gangs ran amok in the city, but managed to fly under the radar. These were Chinese gangs in Chicago. Axios Chicago reporter Monica Eng digs into her own family history to tell the story of these fierce rivals. Her story first aired on Curious City from WBEZ.
