1. Tips for cleaning old soft-shelled turtle:

(1) Lead the old soft-shelled turtle to stick out its head with chopsticks to bite, stretch it after biting, cut off its neck with a knife, and then control its blood.

(2) After killing the old turtle, put it in hot water at about 8℃, scald it for 2-5 minutes, then take it out, and then gently scrape off the black skin of the turtle with a sharp knife. However, don't scrape off the skirt around the old turtle, because it is the most delicious place on the turtle. Then wash the old turtle with clean black skin.

(3) Cut the old turtle from the bottom edge of the skirt and lift the cover of the turtle to remove the internal organs. You can also use a sharp knife to cut a cross in the abdomen of the old turtle, dig out the internal organs and then wash them with water.

(4) After washing the old turtle, cut off the tips and tail sheaths of its four claws and remove the butter attached to its four feet. Because the butter in the turtle has a particularly strong smell, it must be removed.
