Wei Zheng, a politician in the early Tang Dynasty, is said to be a very filial man. His mother had been suffering from cough and asthma for many years. Wei Zheng sought medical treatment everywhere, but to no avail, which made Wei Zheng very uneasy. Somehow Li Shimin, Emperor Taizong of the Tang Dynasty, found out about this, so he sent an imperial doctor to diagnose him. The imperial doctor looked, smelled, asked, and cut carefully, and then prescribed traditional Chinese medicine such as Sichuan clamshell, almond, tangerine peel, and faxia. But the temperament of this old lady is a little weird. She only drank a small sip of the medicine, and she kept saying that the medicine was too bitter and difficult to swallow. You tried to persuade her, but she refused to take any more medicine. Wei Zheng There was nothing I could do to her, so I had to comfort her in every possible way.

The next day, the old lady called Wei Zheng in front of her and told him that she wanted to eat pears. Wei Zheng immediately sent someone to buy the pears, peeled them and cut them into small pieces, put them in a fruit plate and gave them to the old lady. But because of her old age, many of her teeth had fallen out, making it difficult for her to chew. She only ate a small piece of pear and then stopped eating. This put Wei Zheng in trouble again. He thought, let's boil the pear slices in water and add sugar and let the old lady drink the fried pear juice. This worked: the old lady drank half a bowl of pear juice soup and still licked her lips and said: It tastes good! It tastes good! Wei Zheng saw that the old lady liked the fried pear juice soup very much, but how could the disease be cured by just drinking pear juice soup? Therefore, when he was making pear juice soup for the old lady, he poured a bowl of concoction prepared according to the imperial doctor's prescription into the pear soup and cooked the juice together. In order to prevent the old lady from complaining about the bitterness and refusing to drink it, he specially added some more sugar. , stayed up until the third watch. Wei Zheng was also a little tired, so he closed his eyes and rested his mind. When he opened his eyes and opened the lid of the medicine jar, he found that the medicine had been boiled for too long and turned into sugar cubes. Wei Zheng was afraid that the sugar cubes would not taste good, so he tasted a little first and found them fragrant and sweet. Then he sent the candy to the old lady and asked her to taste it. The candy was crispy and melted in her mouth. It was fragrant, sweet, and had a refreshing aroma. The old lady liked it very much. Wei Zheng was happy to see that the old lady liked to eat, so he made candy cubes for the old lady every day using Chinese medicinal juice and pear juice and sugar. Unexpectedly, the old lady's appetite increased after eating like this for nearly half a month. Not only did her food intake increase, but her cough and asthma were also cured.

Wei Zheng cured the old lady's illness with medicine and pear juice. The news spread quickly. Doctors also used this wonderful recipe to treat patients and received good results. People just call it pear candy.
