The second step is to hold the egg in your palm, stop from the "waist" and roll around, and crush all the eggshells around the waist of the egg. But don't use too much force to avoid crushing the inside of the egg. You'd better hear the crack of eggshells.
The third step is to gently tear a small mouth at the broken position, and dig it out together with the membrane inside the egg skin when digging.
The fourth step is to break the eggshell with both hands, and the eggshell can fall off and automatically fall off into two halves. In this way, a complete egg is peeled off.
In fact, the principle is very simple. There is a thin egg membrane between the eggshell and the egg white, and there is a gap between the big egg membrane and the eggshell. If you usually peel the egg with a big head first, if the egg membrane can't be peeled off, it's easy to peel off the egg potholes. In the middle part of the egg, the adhesion between the egg membrane and the eggshell is relatively close, which is more conducive to the separation of the egg membrane from the egg white after rolling, so it is easy to peel off the complete egg membrane and quickly peel off the complete egg.
