Yan Di was an ancient tribal leader. Whether Yan Di was Shennong is still controversial. Some say that Yan Di is Shennong, some say that there may be many generations of Yan Di tribe, the first generation leader is Shennong, and some say that Yan Di is the last generation leader of Shennong tribe, so he fought the Yellow Emperor in Sakamoto. According to the title, it should be understood that Emperor Yan is Shennong. However, Qi Bo was a figure in the era of the Yellow Emperor. In terms of time, their medical intersection is either a connecting link between the preceding and the following, or there is no intersection.

Shennong is a figure in ancient myths and legends, and is regarded as the god of medicine and agriculture. He personally tasted herbs, experimented with herbs, developed herbs to treat diseases, dissolved all kinds of poisons, saved lives, taught people to plant and raise livestock, developed agriculture and laid the foundation for agriculture.

Qibo is also a doctor in ancient legend, named after living in Qishan. His teacher was a doctor during the Shennong period, while Qi Bo learned the nature of drugs during the day and studied health preservation and meridian medicine at night. Therefore, his medical skill is very high. Later, the Yellow Emperor visited Xi 'an and found Zibo in Qishan, so Zibo became the minister of the Yellow Emperor. The Yellow Emperor ordered Zeebe to taste a hundred herbs and study medicine. Huangdi often asked Qi Bo for his medical knowledge. He can ask about the relationship between weather and disease, and he can also ask about the relationship between geographical location and disease. In order to take medicine blindly, he would ask and answer questions, which led to Su Wen. The technique of "Huang Qi" now refers to the answer between Qi Bo and the Yellow Emperor.

In medicine, gas wave has the function of connecting and inheriting the medical culture of Yanhuang. If this Yandi is not another Yandi, Qi Bo and Shennong have no intersection in medicine.
