The Four Classics of the Yellow Emperor, which originated in the Warring States and prevailed in the early years of the Western Han Dynasty, was once a forest of contending schools of thought. Sima Qian didn't see it when he wrote historical records. As a result, Huangxue has been submerged for more than 5,000 years, and has not been paid attention to by historians of past dynasties. The idea of "Huang Lao", which was popular in the Western Han Dynasty, has always been a mystery in the history of China's thought. Now the Four Classics of the Yellow Emperor have been unearthed. After textual research by Mr Tang Lan, it is confirmed that The Four Classics of Huangdi is not a fake book, but the first Huangdi book unearthed in Xuanyuan for thousands of years. This is a book "The Foundation of Governing the Country", which consists of four articles. This provides a reliable historical basis for Chinese people at home and abroad to re-understand Huangdi and Huangdi's thoughts. Xuanyuan Huangdi is no longer a legendary figure, but a real historical figure.

Mr. Wang Hansheng, a 93-year-old historian in Taiwan Province Province, couldn't wait to fly back to the mainland after hearing this exciting news. But at that time, there was no postal service between the two sides of the Taiwan Strait, so it was impossible to see the original. After many twists and turns, a photocopy of the Four Classics of the Yellow Emperor was obtained through Japan. Mr. Wang Hansheng translated The Four Classics of the Yellow Emperor day and night, which was published in Longhua Publishing House of Taiwan Province Province on 1976. Mr. Wang Lao solemnly declared in his preface: "After reading the four books and five classics, we learned the way of monasticism and improved the realm of life. If we are still ignorant, it is irreparable. Even reading thousands of books won't help. Four thousand years ago, my ancestors opened the door to the mystery of the universe and pointed out a way forward. How happy I am to read valuable classics today! " Another cloud says, "It is fortunate that the Four Classics of the Yellow Emperor were unearthed. If the ancestors descend to earth again, all Chinese people should rejoice."

After a lapse of sixteen years, Mr. Yu Mingguang of Chinese mainland also annotated The Four Classics of the Yellow Emperor in 1989, the title of which was inscribed by the late Mr. Zhou Gucheng and officially published by Heilongjiang People's Publishing House. In the preface of the book, Mr. Yu Mingguang wrote: "Huangxue has been neglected for more than two thousand years, and the idea of' Huanglao' popular in the early Western Han Dynasty has always been a mystery in the history of China's thoughts! 1973 The Four Classics of the Yellow Emperor, unearthed from the No.3 Han Tomb in Mawangdui, Changsha, provides a reliable historical basis for us to study and restore the position of this school in history and re-understand the thought of "Huang Lao".

Sima Qian didn't read the Four Classics of the Yellow Emperor when he wrote Historical Records, because he was born in the era of Emperor Wu of the Han Dynasty (Jingdi was the son of Emperor Wen and the father of Emperor Wu, and was in office for 16 years). During the reign of Emperor Wu of the Han Dynasty, Sima Qian angered Emperor Wu of the Han Dynasty and was imprisoned for corruption. His father Sima Yan is an official in North Korea, and his father and son are both officials in North Korea. At that time, Sima Qian was only in his thirties, and the Four Classics of the Yellow Emperor had been buried for twenty-seven years. So when Sima Qian wrote historical records, he didn't see the Four Classics of the Yellow Emperor. Only according to the legend at that time, I wrote the biography of the Five Emperors, ranking first in the historical records.
