Ten famous quotes reveal the truth of human nature:

1. "Buy cheap and sell cheap, get easy and give easy." Things that are too easy to get are often not cherished, whether it is an object or a person.

2. "Once the horse dies and the gold is gone, relatives become strangers." When you are useful, everyone flatters you, and when you are useless, everyone treats you as a stranger.

3. "Since ancient times, people have never been good for a thousand days, and flowers are not red until they are plucked." Life is not always smooth, and sooner or later you will encounter adversity; once the flowers are plucked, they will quickly wither.

4. "If money comes from the world, how can you be poor or rich forever." No one can be rich forever, and no one will be poor forever, and things in the world are impermanent.

5. "Only when gold meets fire can you know its color, and only when people meet money can you see their hearts." When you encounter difficulties, you will know who really loves you; when you are in financial difficulties, you can see who really cares about you.

6. "The door that gave me life is the door that I will die in. I can't bear it when I see through it." Life is destined to have life and death. Although we know that life is limited, we still can't let it go.

7. "Thorns are hidden under the branches and leaves of flowers, and it is difficult to guarantee that the human heart is not poisonous." Everything in the world is true or false, but only the human heart is the most difficult to guess. For the human heart, we must prevent it before it happens.

8. "The car in front has overturned thousands of times, and the car behind has also overturned." Repeating the same mistakes on the wrong road seems to be a common problem for everyone.

9. "Tea is the matchmaker of romance, and wine is the matchmaker of sex." Romantic affairs have a dual nature, and a thought may make a world of difference.

10. "After spending the night with thousands of idle flowers, it is better to go home and sleep with my wife." Even if there are thousands of temptations in the world, going home and sleeping with my wife is the happiest thing. Even if there is no fun at the bedside, there is no need to say more.
