Brush the unclean places with a fine brush, and put the washed crabs directly into the boiling pot, add enough water, then wash the ginger and cut it into pieces, put it into the pot, and add appropriate amount of edible salt.

When eating crabs, dip them in balsamic vinegar and drink some yellow wine, which will make them feel particularly delicious.
