Idiom origin:
Tang Li Shangyin's Biography of Li He: "(Li He) was a slave since childhood, riding a long distance (xū), memorizing ancient tricks, and putting books into the bag when something happened." When I got home at dusk, Mrs. Tai took the maid out of her bag and saw many books. Mo said,' Yes, it is your duty to express your heart.' Later, people extracted the word "bitter songs" from this sentence, and put forward the word "bitter songs" from Han Yu's poem "Returning to Pengcheng", which formed the idiom "bitter songs".
