"Crocodile tears" is a well-known Western proverb. According to ancient Western legends, crocodiles have both a fierce and cruel side and a cunning and treacherous side. When it peeps at people, animals, beasts and fish and other predators, it will often shed tears first, making you feel compassionate, so that you will be paralyzed by the illusion and lose your vigilance against its sudden attack, and be violently devoured by it in an unguarded state.
Another theory is that after the crocodile catches its prey, it will swallow it greedily and weep slowly. In short, this phrase is a metaphor for false tears, disguised sympathy. Later, it was conventionally extended to satirize those who hurt others while pretending to be compassionate and kind.
When the crocodile eats, it has to shed tears, and when people didn't know science before, they thought that crocodiles weep because they were sad to eat something else, and people thought it was fake compassion! In fact, the crocodile is not sad at all, but is removing excess salt from the body. The crocodile that usually lives in the sea drinks a lot of seawater and accumulates a lot of salt, so it uses the function of the organ in the eye socket that specializes in processing salt to concentrate the excess salt, and through the eyes, it flows out like teardrops and thinks that this is fake, and it still means this to this day!
Therefore, the crocodile's tears refer to someone else's fake heart, change heart, but on the surface pretend to be very fake.
