Cut preserved eggs:

1. Silk thread egg cutting method: You can use silk thread to cut preserved eggs, which is even and does not stick to the egg yolk.

2. Hot knife cutting method: scald the knife in hot water before cutting, and the eggs can be cut neatly and beautifully.

3. Boil once and soak twice: Boil the preserved eggs in water and soak them in cold water to cool down. This will allow the yolk of the preserved egg to solidify and cut without sticking to the knife.
