The source of why gourds were placed at the entrance of ancient pharmacies is as follows:

Have you noticed that many ancient myths and legends put elixirs in gourds? For example, the elixir of Taishang Laojun and so on. Ancient pharmacies hung or placed gourds to show that drugs were authentic and precious. 2. Precious Chinese medicines or medicinal materials need to be hidden in a cool and sealed container. ? 3. According to "The History of the Later Han Dynasty, Biography of Fangshu and Fei Changfang", a magical old man came to Chang 'an in the summer of Han Dynasty and opened a small pharmacy with a gourd filled with pills to cure the plague. Where there is a doctor, the old man takes out a pill and lets him take it with warm water. After taking the medicine, the patients really got better one by one. The story spread from one story to another, and it became a much-told story in many places. Later, some medical practitioners took the gourd as the symbol of Chinese medicine shops. Now, many Chinese patent medicines also have the design of the gourd on their trademarks.

4. The original text of The History of the Later Han Dynasty, Biography of Fangshu and Fei Changfang is recorded as follows: "Those who spend a long room are also from Runan. Used to be a city official. There is an old man selling medicine in the city, hanging a pot on the boss's head, and then jumping into the pot.

people in the city don't see it, but they only see it upstairs. It's different, because they go to worship the preserved wine again. Weng knows that the meaning of a long room is also divine, saying, "I can come back tomorrow." On the first day of my life, I will return to Weng, and Weng will enter the pot with me. I only saw the beauty of the Jade Hall, which meant that wine was sweet and delicious, and it was full of profit.

*** came out after drinking. Weng yue doesn't listen to people. Later, he went upstairs to wait for the long room and said, "I am a fairy, and I am responsible for it. What should I do now?

if you go, can Zi Ning go with you? There is less wine downstairs, and I will say goodbye to you. " A long room makes people take it, but they can't win it, and it makes ten people carry it, so it's better not to lift it. Weng Wen laughed and went downstairs, lifting it with one finger. The TV set is like a liter, but they can't drink it all day. "
