The smell of lead acetic acid
There was a scholar in ancient times, who was sensitive and good at studying. One day, I found a strange medicine in the market, white and crystalline in color, and the smell was slightly refreshing.

The scholar was suspicious and wanted to know its taste. Others advised, saying that this medicine may have strange poison, and he was afraid of eating it. However, the scholar was eager to know, so he took a little and tasted it on the tip of his tongue.

At first I felt the taste was a little sweet, but not long after, it was slightly astringent in the throat, and gradually the tongue was numb, and the abdomen was boiling, and the pain was unbearable. The scholar was terrified and cried for help. The neighbors heard it, and the doctor was urgently delayed.

When the doctor arrives, observe its appearance, observe its condition, ask about its feelings, and know how to eat foreign medicines. Then he applied medicine for first aid, poured antidote soup, and made him vomit. After a long time, the scholar's side slowed down a little, his face was pale, and his heart was lingering with fear.

Since then, every time the scholar remembered this matter, he still felt afraid, and often warned people: "The nature of things is unpredictable, so you should not taste it lightly. The smell of lead and acetic acid is a deadly omen, and you must not take risks out of curiosity."
