Fuck you. Where is the dialect? What do you mean?

There is a saying in Sichuan dialect called "dead eyes", which means "be your dead eyes".

In Sichuan dialect, "dead eye" is a person with rigid and inflexible thoughts: so many people can't persuade you, what a dead eye!

"Eye" is the eye, which is the most flexible and elastic. Once the eyes lose their elasticity, they become "dead eyes", that is to say, they are blind.

Sichuanese use "dead eyes" to refer to people who are rigid, inflexible and die-hard, which is quite vivid.
