Chinese civilization is 5,000 years old, before this was just a statement, there is no evidence. Until the excavation of the Liangzhu ancient site, the claim that the Chinese 5,000 years old seems to be confirmed - according to archaeological excavations, the Liangzhu site is around 3000 BC.
There is no doubt that the core area of Liangzhu is in the bottle kiln town of Hangzhou, which was once a highly developed civilization. The ancient city of Liangzhu is very large, and it is impossible to build such a city without a considerable degree of civilization and social organization ability. The water conservancy projects in Liangzhu Ancient City are also very developed, with long dikes. The entire ancient city of Liangzhu is surrounded by water, which is equivalent to building a moat. It's hard to imagine that it was 5,000 years ago, hundreds of years before the legendary Yellow Emperor and YanDi (the official version of Yanhuang in the early Min Dynasty was 4,700 years ago).
But Liangzhu culture has nothing to do with our current Chinese civilization. Our Chinese civilization is inherited by Erlitou, Yanshi Mall, Anyang Yin Ruins... There is an inherited relationship with these. Yin Ruins has a text, and the history after that has documented it, and the Shang Zhou Qin and Han dynasties have come all the way down, in the same vein. Our current Chinese civilization is pushed forward, and in any case, it cannot push Liangzhu.
So the embarrassment is that although Liangzhu is an ancient civilization that has existed on the land of China, it has nothing to do with us, it is not our ancestor.
However, some things depend on how you interpret it. Even if Liangzhu is not our ancestor, we can say that it is one of the sources of Chinese civilization, saying that it is inextricably linked to the three generations of Xia Shang Zhou culture, just like Sanxingdui.
It is very easy to find a little connection, we can even find contact with the Incas, the Aztecs from the ancient Chinese civilization, we can find the connection with Africa, we can find the connection with the Eskimos... You can also use a book like the Classic of Mountains and Seas to prove the connection with the whole world.
If you hold the idea that hundreds of rivers flow to the sea, then all the ancient civilizations that have existed on the land of China can be used by me. It's just that some rivers dried up as they flowed to the sea, such as the Liangzhu civilization.
