There are many profound words in classical Chinese. Details are as follows.

1. "The Book of Songs, Wan Feng·Xiang Mouse", the Xiang Rat has skin, but humans have no manners. If a man has no manners, what will he do if he does not die? Rats have teeth, but humans have teeth. There is no end to human beings, and there is no need to wait until death. Rats are physical, but humans are rude. If a person is rude, he will die.

It means that even mice have fur, how can we be without dignity as a human being? How can we be without dignity as a human being? What else can we do if we don’t die? Look at mice, they all have teeth. If a person doesn’t have any sense of shame, if he doesn’t have any sense of shame, why are he waiting for death? See, mice all have limbs. If people don’t have moral education, why don’t they die quickly?

2. Mother, sincerity is not pleasing to the mother. I mean, he's really unhappy.

3. I have an old friend with a dick like yours, and now his grave is covered with green grass. It means I once had a friend who was as bad as you, but he is dead.

4. Inhumane. It means that people are really nothing but dogs.

5. Ju Zi, his mouth can produce ivory. It means brat, can you spit out ivory from your mouth?

The allusions of ancient celebrities using classical Chinese to satirize people's words are as follows,

1. Du Fu, a great writer of the generation, was furious when he saw the poems written by deceivers in front of Li Bai's tomb criticizing Li Bai. Angry, he said, "Your body and shape will be annihilated, and the eternal flow of rivers will not be wasted." The poet's actions are indeed extraordinary. Although the results are not dirty, they are filled with hatred and hearty, which is difficult to match in ancient and modern times.

2. Of course, ancient literati are not seen on the streets without using curse words. The great writer Su Shi said that the Buddha's seal is like a piece of shit. But Foyin said, when I visited the Buddha, I saw that you are a Buddha. Su Xiaomei's explanation is that the thoughts in the heart are transformed into external objects, that is, there is a Buddha in Foyin's heart, and Dongpo's heart is like stinking feces.
