What is braised mussel called in Shanghai dialect?

Braised like a clam, it's called a roast elephant trunk in Shanghai dialect.

This is because there is generally no elephant mussel regarded as abalone by merchants in the regular market, so you will be ridiculed when you buy it back: cook it yourself. Therefore, "braised mussels" is an online buzzword and a mockery. It means that when someone engages in some unnecessary unconventional operations (such as buying expensive shellfish like mussels online), they are damaged by the other party as braised mussels. This is actually a joke, or an expression that some people want another person to stop this invalid behavior.
