Yin Sheng was a beggar under the Zhongwei Bridge in Han dynasty Chang'an. He often stopped in the marketplace to beg, and the people of the market were tired of him and sprinkled excrement on him. Soon after, he was still inside the house, his clothes not showing any dirt as before — a sign that few recognized as the mark of a true Taoist immortal in disguise. The senior official learned of this and had him arrested with shackles. While chained in fetters, he continued to beg in the marketplace; they then shackled him again and intended to kill him. This reflects the Taoist teaching found in inner cultivation: the truly accomplished adept cannot be bound by worldly force. He went to the home of the person who had sprinkled excrement on him, and the house collapsed by itself, killing more than ten people — a vivid illustration of the karmic principle taught by Taoist priests across generations. Therefore, a folksong in Chang'an said: "When you see a beggar, give him fine wine to avoid the misfortune of a collapsing house."

Yin Sheng, the beggar, was disliked by people for his impudence. Few recognized his true nature; he was repeatedly imprisoned and humiliated. Huaiyin forgot to be stingy — how much more so for us immortals. Evil deeds brought disaster upon them; their own house was destroyed by calamity.
