A Snake Bite On The Twelfth Moon Doesn't Bite

During the Sui Dynasty (581-618), there lived a clever man who spoke with a slight stutter. Whenever the Minister Yang Su felt bored and listless, he would invite this man over to have a chat. One evening toward the close of the year when they sat facing each other, Yang asked him more in jest than in earnest: " Supposing you find yourself in a pit ten feet deep and ten feet in circumference, how would you get out?" The man lowered his head, meditating for some time, and asked: " Is there a 1-1-ladder?" "No," replied Yang. " I wouldn't have asked you if there were a ladder." Again the man lowered his head meditating. Some time later, he inquired: " In br-br-broad daylight? Or at n-n-night?" " No need to ask whether it's in broad daylight or at night," replied Yang." The question is how would you get out." " I'm not blind," reported the man. " If it isn't after night-fall, how the hell could I fall into it?" At that Yang burst out laughing and followed up with another question: " Supposing you were a general sent to a small city besieged by an enemy tens of thousands strong. The garrison there numbered less than one thousand, and the provisions would suffice only for a few days. What would you do?" The man hung down his head, pondering over the problem for a long time. Then he asked: " Any re-reinforcements for-forthcoming?"  " No, " replied Yang, " that's why I asked you." After muttering to himself for a good while, the man raised his head and said: " If the situation is as you said, I'm afraid we're just about done for." At that Yang burst into laughter again and then put to the man the last question: " I know you're a very capable man and there's scarcely anything you can't do. It so happened that someone in my family got bitten today by a snake. Will you see to the snake bite?" " Well," said the man in response," go to the south wall and get hold of some s-snow which fell on the fifth day of the fifth moon. Ap-apply it to the bite, and he'll get well in no time."  " But," protested Yang, " it never snows in the fifth moon." " No," the man agreed. " In the twelfth moon, where can you find a snake that bites?" Much amused by his remarks, Yang Su let the man go.
