counter-example
There is a fable in the Buddhist sutra Baiyu Jing: Once upon a time, there was a man who first filled an urn with grain. Camels eat food in the urn, but they can't go out. If you can't get it, you think you are worried. An old man came up and said, "Don't worry, I'll teach you how to get out. If you use my language, you will come out soon. You should behead yourself and get it. " If you use it, behead it with a knife. Kill the camel and break the urn. So stupid that everyone laughs. Generally speaking, once upon a time there was a man who held Xiaomi in an urn for the first time. The camel put its head into the urn to eat millet, but it couldn't come out, which made it very angry. An old man came up to him and told him, "Don't worry, I'll teach you a way to get the camel out." . If you listen to me, you will come out soon. If you cut off the camel's head, the camel will come out naturally. "So he listened to him and cut off the camel's head with a knife. He broke the urn after killing the camel. Such a stupid person is laughed at.
The camel's head is stuck in the urn and can't get out. To save a camel, you must break the urn, but to save an urn, you must catch a camel. Either way. The people in the story took a stupid approach and lost both. Such a thing naturally does not appear in real life, but we often face this similar dilemma. Due to improper handling, we will lose both sides.
