2. Preheat the pot on medium heat, add a little oil, beat a fresh egg into a small bowl, and slide it into the pot on low heat. If the egg white bubbles immediately after the egg slides in, it is too big and should be turned down. The best state is that there is no foaming, but the egg white begins to turn white immediately. Turn down the fire, then sprinkle some salt on the surface of the egg immediately after it is put in, then cover it, and slowly stew the surface of the egg white by using the steam of the egg itself and the heat emitted by the pot.
