In March 2021, a wave of Taiwanese people changed their legal names to include the Chinese word for salmon (鮭魚, guīyú) to take advantage of a promotion by the Japanese conveyor belt sushi chain Sushiro. The chain offered free sushi to guests whose names included the word. This phenomenon was dubbed the "salmon chaos" by English-language media.[1] The incident garnered significant criticism by public figures and the general population.
