There is an idiom that people can hear and recite, called the world is as black as a crow; there is also a familiar word, called crow's mouth. I don't know why the bird "crow" is so reprehensible that it is almost self-contained.

Ever since I can remember, I've had a deeply repugnant trait: every bad thing that comes out of my mouth can't help but be perfectly embodied. It is the legendary "good spirit that does not work bad"! I've tried a few times, and slowly I've reached a difficult point. Later, I learned to be smart and never made any more assertions.
How I want to be a white crow! If this wish comes true, I can achieve "bad spirits and bad spirits"! I will let the communist society be realized early, so that the people of the whole world can live a carefree and free life; let the phrase "no trade, no harm" disappear completely on the earth; let the North River of the Arctic no longer melt, and give the polar bear a beautiful home to live... Suddenly, a hasty bell rang in my ear, and I slowly opened my eyes... ay! It turned out to be a dream again! [Crying is silent] [Crying is silent] [Crying is silent]
