How 'Cali' became a slur among Vietnam's growing army of nationalists
Last fall, Vietnam opened a sprawling new military museum here, and among thousands of artifacts in the four-story building and a courtyard filled with tanks and aircrafts, one exhibit quickly became the star attraction: the flag of South Vietnam.
The government regards the yellow banner with three red stripes as a sign of resistance to the communist regime, violating laws about inciting dissent. With few exceptions, it is not displayed.
Reactions to the rare sighting soon went viral. Young visitors at the Vietnam Military History Museum posted photos of themselves next to the flag with deep frowns, thumbs down or middle fingers raised. As the photos drew unwanted attention, the flag was unpinned from a wall and folded within a display case. Social media content featuring rude hand gestures was scrubbed from the internet.
But the phenomenon persisted.
Several weeks ago, schoolchildren who were on tour made it a point to check out the flag. Every few minutes, a new group crowded around the banner also known online as the Cali flag holding up middle fingers or crossing their hands to form an X.
