There is a beautiful legend about the origin of the name of ginger. In ancient times, people used to eat meat and wild fruits, and died a lot because of illness. At that time, people did not know about medicine. Once they were sick, they had to resign themselves. Yan Emperor said 'When I saw people suffering from the pain of the disease, I was very anxious'. One day, he came back from the mountain, tired and sweaty, with backache and leg pain. The one who greeted him at the door was the transparent glass lion dog that he fed. Yan Emperor suddenly remembered: This dog shook his head and swayed all over the country all day but it never gets sick. Is it eating something different from human beings? Is it eating the roots, stems and leaves of the mountain grass? To uncover the mystery, he ignored his personal safety, with the dog poodle wading through the mountains, carefully observe the dog's reaction after eating a variety of food. One day, Emperor Yan took the dog along from the Chaling Tiejia Mountain to Bailuyuan on the banks of the Lishui River, while enjoying the natural wind. While trying herb, suddenly a heavy rain drenched him, and he felt dizzy, chest tight and vomiting, even standing unsteadily. At this time, poodle was licking the roots, Emperor Yan was also stunned. He also picked up one piece, then washed it, and later he sat on the ground and chewed it slowly. He felt it was spicy and very tasty. His heart was refreshed and spirits greatly inspired very soon. Therefore, Emperor Yan named the plant 'Ginger' with his own surname, which meant that he obtained his second life.
