According to your description, it is a hairy crab. The easiest way is to cut it in half (cut it vertically from the middle). After the oil is hot (add some salt appropriately), dry-fry it directly with the cut side down, etc. After the crab turns slightly red, add some red wine, then cover the pot and simmer until cooked (about 3 minutes if the heat is high), it is quite delicious.
Of course, you can also steam it directly in a steaming tray with water until cooked, and then add vinegar to eat it. However, I personally think the taste is average, and it is still delicious when fried. Be sure to add more red wine for frying. Give it to me. Best answer, haha....
