The Fool of the Hundred Parables of the Book of Fools collects the parables of cow's milk

: Once upon a time, there was a foolish man who was going to feast on guests. He wants to accumulate some milk so that he can enjoy it when it arrives. He thought to himself, "If I milk the milk first every day, more and more milk, there will be nowhere to put it, and maybe it will rot and deteriorate." It would be better to let the milk be stored in the belly of the cow and squeeze all the milk out on the spot at the banquet. He made up his mind, so he took the cows and the nursing calves to different places to feed them. After a month, he set up a feast for the guests, at which time he pulled the cow out to squeeze out the milk, but by this time the cow's milk was dry and nothing could be squeezed. Suddenly, the guests in the hall were angry with him, and some laughed at him.

The same is true of other fools. They wanted to practice through generosity, but they said, "Wait until I'm rich and rich, and then give it all at once." "But before the wealth has accumulated, it has either been robbed by county officials, water and fire, or thieves; or it is suddenly at the time of death, and the time of life is hurried, and it is too late to give alms." Just like the fool who has accumulated milk in the belly of a cow but has found nothing.
