Longzhili is a kind of natural herbal drink, which is made from herbs of many precious plants such as ginseng. According to legend, Qin Xiaogong, the famous monarch of Qin State, died of "overwork and exhaustion of essence". At that time, Bian Que, who happened to travel around the world, came to Qin. In the face of Qin Guojun, who worked hard all his life and had lofty aspirations, Bian Que found that he was all well, had a high fever and was getting weaker and weaker. At this time, Qin Xiaogong was tired. Bian Que felt guilty about this, so he began to think and study how to strengthen the body, replenish the brain, relieve fatigue and restore physical fitness. As a result, prescriptions containing ginseng, astragalus and Polygonatum sibiricum began to appear. Bian Que tried rare herbs from different countries. After several years of hard work, a health-preserving decoction with the main effect of "strengthening the body and consolidating the foundation" came out.
