Once upon a time, there was a young man named Li Hu in Lizhuang, Jinzhou, Hebei. He has a strong body and great strength, but for some reason, he has bloating. Although he was treated by the doctor many times, he never got better. His wife was very anxious and finally invited an old doctor from Luzhou, Shanxi Province to Hu. After reading it, the old doctor wrote a prescription: "decoct with wild trumpet flower seeds."

Mrs Li Hu had never heard of this medicine, so she had to come to the door again and tell the old doctor about it.

Hearing this, the old doctor said, "I have this kind of wild flower in front of my hometown in Xinzhou, Shanxi, and its seed is this medicine." You can send someone to my house to get it. " Mrs Li Hu rushed to Shaanxi to collect wild morning glory seeds. Li Hu was given several doses of decoction, and it really worked. Li Hu recovered within a month. To thank the old doctor for saving his life, Li Hu took a cow to the old doctor's house. Thanks a thousand times, he wanted to give the cow to the old doctor and asked, "Grandpa, what medicine did you give me?" The old card shark is difficult to answer at the moment. It turns out that this wild morning glory has no name yet. Now when Li Hu asked, the old doctor thought: This kind of flower seed can cure incurable diseases and bring cows. Today, the patient brought the cow home, so we might as well call it "morning glory"! After that, he pointed to the wild morning glory at the door and said, "This is called morning glory. It gives you morning glory seeds, and you just care about the morning glory. " Since then, this wild morning glory has the name "Morning Glory"
