From dawn, sweep the courtyard, clean inside and outside. At dusk, rest, close the door and behave yourself. A porridge and a meal are hard to come by. It's hard to keep thinking about things. It is better to prepare for a rainy day than to dig a well when you are thirsty. Self-help must be frugal, and banquets must not be delayed. The utensils are clean, and tile is better than jade. The more exquisite the diet, the better the vegetables in the garden.
