They say that when you have money you can even get a gui to work a millstone, but if on the other hand, you tell a "lazy-gui" to do something, then it's like "asking a gui to treat the sick," or "ushering a gui into your abode," in which case the more they help the busier you end up.
雖說有錢能使鬼推磨，若是叫到「懶惰鬼」來做事，那也是「請鬼看病」、「引鬼入宅」，所用非人、越幫越忙。
