The first couplet is: "The heart is as bright and calm as the bright moon." The first couplet compares the heart to the bright moon. The moon has been endowed with the two characteristics of brightness and tranquility since ancient times, and it has rich connotations! The human heart should be as bright as the bright moon and be able to distinguish right from wrong; it should be as quiet as the bright moon and be peaceful and far-reaching! Okay, let’s take a look at Xia Lianjia, right?
Aspiration is as thick as a rock and strong.
The first couplet writes about the heart, and the second couplet writes about the aspirations! Comparing a person's ambition to a rock, what is a rock? That is, thick, large and hard stone, which means steadfastness! Aspirations are as solid as a rock. We should have lofty (thick) ambitions, strengthen our ambitions, and fight for them!
The meaning is as light and clear as a leisurely cloud.
In a simple life, nothing is better than leisurely clouds and wild cranes!
The Tao is as bitter as strong tea, yet mellow.
"If you hear the truth in the morning, you will die in the evening!"
You are eloquent and straightforward.
To be eloquent means to speak eloquently, like a waterfall that keeps pouring!
