Interpretation of "Ears" in Wolf

Stopping laughing means just adding a joke. The source is Pu Songling's Wolf. (Not the "Wolf" in Bosongling as mentioned upstairs)

The original text is as follows:

Ah Zai came home late, and all the meat in his burden was eaten, leaving only bones. On the way, the two wolves traveled a long way. Eliminate fear and throw it at the bone. A wolf stopped with a bone, but a wolf still threw it back. The last wolf stopped and the previous wolf came again. The bones are exhausted. And the combination of two wolves is the same. Tu was embarrassed. He was afraid of being attacked by the enemy. There is a wheat field in Gu Ye, where the landowner earns a lot of money. Tu Naiben leaned against it with a knife on his shoulder. Wolves are afraid to go forward, eyeing each other. When I was a child, a wolf left and a dog sat in front of him. After a long time, my eyes seem to be useless and very idle. Tu suddenly and violently, one knife to cut the wolf's head, several knives to kill it. Just want to go, turn to the salary office, a wolf hole, which means tunnel to attack the back. The body is half in, and only the tail is exposed. After the slaughter, he died of a broken stock. It was the wolf who fell asleep before enlightenment, and covered it to lure the enemy. The wolf was afraid, too, but he was killed twice in an instant. What is the geometry of the beast? Stop laughing.
