There are many ways to divide the so-called "up and down".
One, "?" Shang refers to a historical era with some myths and legends, which are recorded in historical books, but it is absurd. In reality, some historical relics have also been unearthed in archaeology. And "Xia" refers to a record with exact time and age, and there are almost no historical disputes and doubts.
Secondly, the division of "Xia Shang" is "AD 1". 1 is preceded by the top, followed by the bottom. In fact, "AD" is the western calendar method. This calendar takes the birth of Jesus as the first year. Before the birth of Jesus, it was called BC. The western calendar is widely used in today's world.
From the early years of the Republic of China, AD gradually entered China. Now it has been used more than the Chronicle of the Yellow Emperor in ancient China, even for a long time. Pay equal attention to lunar calendar.
Third, five thousand years refers to five thousand years of slave society and feudal society in China, and there is no specific time division.
Up and down, there is no specific concept of time division, just an adjective? , is the sum of the history of China; . China? The explanation of "five thousand years of history" is that "the history of China is five thousand years".
All in all, "up and down for five thousand years"? The division of China is not an era, but a symbol of national history.
