When the Yellow Emperor heard his name, he immediately went to visit Kongtong Mountain and wanted to ask him how to get the Tao. At this time, Guang was already 1200 years old, but the result was rejected. Visible wide is not a general willfulness.
However, the Yellow Emperor did not lose heart and came back a few months later. This time, Guang was moved by the sincerity of the Yellow Emperor and told him the essence of Tao. After his inspiration, the Yellow Emperor gradually understood the meaning of Tao. Although he failed to become an immortal, he lived 100 years old.

Huangdi Neijing was called one of the "Seven Medical Classics" by historians in the Western Han Dynasty. According to "Hanshu Yiwenzhi", "Huangdi has eighteen volumes of internal classics and thirty-seven volumes of external classics; Bian Que has nine internal classics and twelve external classics; White "Neijing" 38 volumes, "Waijing" 36 volumes; The next twenty-five volumes. There are seven positive medical classics. "
Textual research in ancient medical books says that the internal and external classics of the Yellow Emperor are "the hexagrams of the Book of Changes, the internal and external versions of the Spring and Autumn Period, the internal and external versions of Zhuangzi, and the internal and external versions of Han Fei", which is not a complete book.
China Traditional Medicine, the encyclopedia of China compiled by 1992, also confirmed again under Huangdi Neijing: "The art and literature of the Han Dynasty are known as external classics, but the internal and external are only relative differences". The above information shows that at least in the Han Dynasty, Huangdi Neijing and Huangdi Neijing were handed down at the same time.
