Why is the term "big crocodile" used in Chinese to describe financial oligarchs? Crocodiles are cold-blooded and patient enough to remain motionless for long periods, reducing their metabolism by pretending to be dead, waiting for prey. When hunting, they lurk underwater in calm waters; once the prey relaxes its guard, they strike a fatal blow. Crocodiles do not chew their food; they swallow it whole or tear it apart by rolling in death. When trading, you should learn from crocodiles, not from monkeys in the trees on the shore.
