Heroes, last time I saw someone write a lot of poems about putting them in the toilet. . Toilet culture, interesting poems!

Once a great calligrapher went on a trip and saw that the ground in the toilet was dirty, so he wrote a sentence on the wall: "Don't pee anywhere". Later, a young man saw it and thought it was too good, so he extended it, changed the order and became a very philosophical sentence, which was posted in the study: "Don't be careless about small things."
