During an anti-corruption training session, an elderly professor shared a story about weasels on the Mongolian grasslands. Weasels are constantly busy searching for food and storing their surplus in burrows. It is estimated that a single weasel can build over 20 "granaries" in its lifetime, enough to feed a dozen other weasels for a lifetime. However, the professor posed a puzzling question: "Do you know how weasels eventually die? They starve to death!" The students were baffled. The professor explained that when weasels reach old age and become less mobile, they retreat into their granaries. To eat, they must constantly gnaw on hard objects to wear down their ever-growing incisors. Unfortunately, because they focused solely on storing food and neglected to store hard objects for tooth maintenance, their teeth grew too long, making it impossible to eat. Consequently, they starved to death amidst their abundant food supplies. The professor noted that weasels are intelligent animals, but they do not die from stupidity; they die from greed. Greed makes them focus only on the food, causing them to overlook the necessary stones and everything else. Trapped by their own greed, they become blind to potential dangers and the future, ultimately being consumed by their own desires.
