According to the "Lu's Spring and Autumn Annals", a crow flew to the door of a wise man. When the wise man saw the crow, he asked it,"You are a crow. Why did you fly to my door?" "I heard that there's a very blessed acupoint in front of your door, so I wanted to take a look." The wise man nodded and said to the crow,"You are a man of insight to come to me for advice." But what you see is not the real blessing because this is an acupoint and not a pit." The crow was a little confused by the wise man's words, but it continued to move forward. On the way, he met a fox. The fox said to the crow,"What are you looking at?" "I heard that there's an acupoint in front of your door, so I wanted to take a look," the crow replied. The fox smiled and said,"Be careful. If you see this acupoint, you will be cursed by it." The crow was a little afraid when she heard the fox's words, but she continued to move forward. Finally, the crow came to a mountain forest where an old man was feeding the pigeons. The crow saw the old man and asked,"May I ask why you are feeding the pigeons here?" The old man smiled and said,"I have a treasure here, but it needs a container to store it." So I'm feeding the pigeon here and waiting for the day I take it somewhere else." The crow suddenly thought of the acupuncture point that the wise man had mentioned. So it said,"You have an acupoint here. If it is dug out, you will be cursed." The old man was surprised by the crow's words and asked,"Where can I have a curse?" The crow said," Because your acupuncture point here is a very blessed acupuncture point, when you dig it out, it will attract bad things to happen. As I said before, this is an acupoint and not a pit." The old man finally understood his mistake. He immediately stopped digging and wished himself good luck.
