What do the images of liver, gallbladder and intestines in China's classical poems mostly represent? For example, inch by inch tears into powder and heartbroken.

In ancient times, the so-called "heartbroken" means sad or depressed. In fact, there is a lyric that says well, "You have no complaints about heartbroken when you do this." That's what it means, I think you know; The so-called brave, basically in ancient poetry or prose, represents courage or another representative character, such as Zhao Zilong is heroic and brave. As for the stomach, spleen and kidney, I have never seen them. It seems that I'm afraid of something, just like Li, who won't let me take the exam and says he's afraid of his father, I don't know anything else.
