There is a person who opens a medicine shop for the first time, and he comes out one day. ． ． ． ． explain

There was a man who had just opened a pharmacy. One day he had to go out for something, so he asked his son to help look after the pharmacy. A man came to the drug store and wanted to buy achyranthes, chicken feet and yellow lotus. However, the man's son was very ignorant and did not know about herbal medicine. He searched all the medicine boxes but could not find these three herbs. So, he So he cut off one foot of the ox that he used for farming. He also cut off the feet of two chickens that he raised and sold them to the customer. When his father came home and asked him what medicines he had sold, he told his father about it. After hearing this, his father smiled helplessly and said with a sigh: "If the customer buys Anemarrhena, Beibei, When you are pregnant, you are going to sell your mother too!" (Achyranthes, chicken feet, yellow lotus, anemarrhena, and Fritillaria are all names of Chinese herbal medicines)

Am I too much? I'll tell you later, whether it's a score or not, please...hehe...
