How many years has the history of Longshui Lake in Chongqing been?

We have been taught the history of China for 5,000 years since childhood, but this is a legendary history including three emperors and five emperors, so strictly speaking, these legendary histories are not allowed to be counted.

So when did the history of China begin to be calculated? Scholars in China and Japan generally date from the Xia Dynasty, so the history of civilization in China is about 4 100 years. In addition, European scholars believe that the history of China's civilization should be only 3700 years, and this algorithm started from the Shang Dynasty.

Why do European scholars think that China is shorter? Only 3700 years, which is actually closely related to the current archaeological discoveries. Before Oracle Bone Inscriptions's discovery, Historical Records was always regarded as a book of the same kind as Shan Hai Jing. Those ancient dynasties were just legends, and the Shang Dynasty did not exist. It was a legendary dynasty in which gods and men coexisted. So the history of China was only 3000 years before the Shang Dynasty was proved. After the discovery of Oracle Bone Inscriptions, the position of Historical Records in people's minds has changed a lot. At one time, they even thought that all the records in Historical Records were facts, and almost 100% affirmed the existence of the Xia Dynasty-the Xia Dynasty existed, but it backfired. Later, no evidence of the existence of the Xia Dynasty was found in the study of Oracle Bone Inscriptions and the archaeological discovery at the scene, and even the word "Xia" in Oracle Bone Inscriptions was not found. Oracle Bone Inscriptions is a milestone of Chinese civilization, and it has been developing and improving constantly. Oracle Bone Inscriptions has about 4,500 words, with rich records, mostly for divination and singing praises to the king. Imagine, praising the king has not achieved the same achievements as summer.

In addition, the book Shangshu, which records the summer, proved to be a fake book, which is not credible. The chronicles of bamboo books are also full of loopholes, which is not credible. Field archaeology has not found any evidence that can directly prove the existence of summer.

As far as the author is concerned, I still believe in the existence of summer. The history of civilization in China is about 4 100 years. Welcome everyone to discuss together.
