What you want to ask is how to write the seven-rhythm poem of drinking mutton soup in rainy days. The seven laws of drinking mutton soup on rainy days are written like this: "On rainy days, the delicate rain is falling, the eaves are dripping, and the thoughts are deep through the years. The sound of rain falls, the heart is as calm as water, and the faint fragrance floats, which warms the heart. A bowl of mutton soup, warm on the tip of the tongue, full of taste, full of feelings. Steaming, singing and laughing in the rain, all the beautiful things in the world are found in the rain. "
