Two tortoises were sitting head to head, absolutely motionless, at the edge of a rice field. Seeing this, an expert asked an old farmer nearby, “What are they doing?” “They’re having an endurance test against each other. The one who first moves will be the loser,” replied the farmer. Pointing at the tortoise with ancient-looking scripts on its back, the expert said, “According to the studies that I have been doing for years, this tortoise has been dead for more than five thousand years.” Hearing this, the other tortoise stretched out its head and said angrily, “Oh, fuck, died already? You should at least have informed me! I’ve been wasting time competing with a dead tortoise!”  Without waiting for the words to settle in, the tortoise with inscriptions stretched out its head and laughed out loud, saying, “You lost, dude! How should you believe what an expert says?”
