The saying "up and down for five thousand years"

China has a long history. According to the ancient tradition, there was China in 2000 BC, with a history of about 4,000 years, which is usually called "five thousand years up and down".

In the 5,000-year history, there are many touching and meaningful stories. Many of them are recorded in writing. As for the ancient situation five thousand years ago, there is no written record, but some myths and legends are circulating.

Myth is just a myth after all, and no one will believe that there is such a thing. But people like this myth. Speaking of history, they often say that it started with "Pangu created the world". This is because it symbolizes the great spirit and rich creativity of human beings to conquer nature.

So, where should human history begin? Later, with the development of science, the fossils excavated from the ground proved that the earliest ancestors of mankind were apes transformed from ancient apes.

Chinese scientists have unearthed many ape-man skeleton fossils and relics all over the motherland, and we can see that the earliest primitive humans in China have a history of more than one million years. Yuanmou ape-man found in Yunnan, about1700,000 years ago; Lantian ape-man unearthed in Shaanxi is about 800,000 years ago. Take the famous Peking man as an example. It has a history of 400,000 to 500,000 years.

Up and down five thousand years is just a name, not to say that China has a history of five thousand years, but it has been hundreds of thousands of years since ancient times.
