The expression "stewed mushrooms" originated from the Hong Kong police. At that time, the status and treatment of policemen in casual clothes were higher than those in police uniforms, and the police's big hats really looked a bit like mushrooms. Therefore, once a civilian policeman wears a police uniform, it means being demoted, so it is called "mushroom stew". Later, not only the police, but also the working class was demoted, which was called "mushroom stew"
