Qi Am (human name) kept a cat in his house, and thought it peculiar himself. To others the cat's name was: "Tiger Cat". A guest suggested, "The tiger is indeed mighty, but not as mighty as the dragon's divine power; please rename it Dragon Cat." Another guest suggested, "A dragon is certainly more powerful than a tiger, but a dragon must fly up to the sky on a cloud, and isn't a cloud more powerful than a dragon? Why don't we rename it Cloud Cat?" Another guest suggested, "Clouds can cover the sky, but when the wind blows, it scatters, so clouds are not as powerful as the wind. It should be renamed Wind Cat." Another guest suggested, "When a gale blows, a wall is enough to shield people from the wind, so how can the wind be compared to a wall! Call it the Wall Cat." Another guest suggested, "Although the wall is strong, as long as the rats make holes in it, the wall will collapse, how can the wall compare to the rats! Just call it the rat cat line."
