How many years has acupuncture been used in traditional Chinese medicine?

According to textual research, it originated from the clan commune system in the primitive society of our country.

There have been human activities in China since 4 million years ago, from about 40,000 years ago to the clan commune system, and continued until 4,000 years ago.

The ancestors of this era used stone tools as their main production and living tools, so it was called the Stone Age in archaeology.

From ancient times to 1000 years ago, it was the Paleolithic Age, from 1000 years ago to 7 million years ago, and from 7 million years ago to 4,000 years ago, it was the Neolithic Age.

Acupuncture therapy was born in the Neolithic Age.

There are some legends about the origin of acupuncture in ancient books, all referring to this era.

For example, as recorded in Huangfu Mi's Century of Emperors, teacher Xi Shi "tasted hundreds of kinds of medicines and made nine needles", while Miro's History of Taoism said that teacher Xi Shi "tasted grass to cure people's diseases".

Huangfu Mi's Preface to Acupuncture A and B says: "The Yellow Emperor visited the followers of Qi Bo, Gao Bo, Yu Shao ... and what did acupuncture do", while Sun Simiao's Preface to Emergency Money said: "The Yellow Emperor was ordered to make nine needles".
