A person's carelessness can be described as "carelessness". Where does the word "carelessness" come from?

The word slovenly generally describes people's carelessness. Actually, this is a common saying. So what is the origin of the word sloppy? It comes from a less beautiful story. This story happened in the Song Dynasty. There was a painter in Bianliang, Kyoto. He usually paints as he pleases, without any rules. When others see his painting, they can't figure out what it is.

Once this man just drew a tiger's head. Just as he was about to draw down, a man came and asked him to draw a horse. He picked up a pen and drew the horse's body under the tiger's head. When the appointed time came, the person who asked him to paint asked him what he was painting, and the painter said it was average.

The buyer of this painting was very angry after hearing his answer. He neither gave him money nor took the painting away. So the painter took the painting home. He put it in the hall. The eldest son asked him what it was. He said there was a tiger in it. The younger son asked him what it was, and he said it was a horse, and both brothers believed it.

The eldest son went hunting outside and took someone else's horse as a tiger, so he took an arrow and shot it dead at once. The painter can only apologize to the other party and compensate others for a horse. The youngest son met a tiger while playing outside. He thought it was a horse and wanted to ride it. The tiger bit him to death. The painter was very sad, so the word sloppy came into being. I didn't expect such a sad story behind this common sentence. It's really sad.
