Hello, Gan Long made a couplet with watermelon, but Ji Xiaolan didn't do it right. He also said that "no one in the world can do it right". The couplet says: "Sit north facing south, eat watermelon, and plant seeds to the east" refers to the emperor, which is static and contains two spatial directions; "Eating watermelon" is dynamic, not only doing one thing, but also including a direction; "The seed goes east" is also dynamic, including doing another thing and a direction. There is a mystery in this couplet, not that Ji Xiaolan can't write well, but that he dare not write well. Even if there is a corresponding pair, you can't say. I hope you are satisfied with the answer!
