Eat a bastard!

Prepare three eggs, separate the egg whites and yolks, and place them in two separate bowls.

Cut each salted duck egg into six pieces, and cut the century egg into six pieces as well.

Start by beating the egg whites in one direction, and use a spoon to remove any foam from the beaten egg whites.

Brush oil on the lunchbox with a brush to remove the mold, then put the salted duck, egg, and century egg into the oiled lunchbox.

Put the beaten egg whites into the container with the arranged century eggs and salted duck eggs, cover with plastic wrap, and poke a few holes with a toothpick.

Steam on the stove for ten minutes.

Then put the beaten egg yolk into the lunch box, and steam for ten more minutes.

A jade-like bastard is done.
