There are five sons in the west, one is simple, the other is sensitive and the other is blind. What do you mean?

Westerners have five sons. A child is simple, a child is sensitive, a child is blind, a child rolls for grain (pronounced twice, hunched), and a child is lame. Is to let the simple farmer, sensitive Jia, ignorant Bu, rolls for grain. Bend over at work), the lame spin (spinning without feet), and five children don't worry about food and clothing. The neighbor in the west has five sons. My son is honest, intelligent, blind, hunchbacked and lame. Let honest farming, smart business, blind divination (fortune-telling), hunchback rubbing hemp rope, lame spinning, five sons do not worry about food and clothing. Truth: make the best use of everything and people make the best use of it.
