Mencius said, "If you don't go against the farming season, you can't beat grain." If you don't count, neither fish nor turtle can be eaten. Axes can get into the mountains in time, but wood and wood can't be used. Grains, fish and turtles can't be eaten, and wood can't be used, which makes people feel sorry for health and death. There is no regret for their birth, illness and death, and the beginning of the king is also. Five acres of houses, the trees are mulberry, and fifty people can wear clothes and silks; Chickens, dolphins and dogs are all domestic animals, so there is no time to waste. Seventy people can eat meat; A hundred acres of land, if you don't hurry, a family of several can be hungry; I would like to show filial piety to the teaching of the mission, and the winners will not be put on the road.
