According to textual research, although Liangzhu culture has no written records, it can be inferred from many sites that its existence time was about 3300 BC, which lasted until 2000 BC, and the sudden disappearance of civilization ended, with a history of about 1300 years ago.
During this period, Liangzhu people created a splendid civilization. First, the development of military strength, as recorded in Guanzi, "becomes a country of doves" ... the soldiers are strong and the world is invincible. Second, with the development of farming civilization, many tools similar to plows have been found in unearthed sites; Third, the development of jade craft. There are many kinds of jade found in the site, including jade, jade, jade and so on.
I think the Liangzhu people who created such brilliance suddenly disappeared because their homes were destroyed by the floods caused by climate change at that time.
The reason is that Liangzhu culture is located in the middle and lower reaches of the Yangtze River, and the terrain is low in the whole country. However, due to climate change, glaciers in the upper reaches of Liangzhu culture melted and rainfall increased, causing floods and destroying homes.
A large number of Liangzhu people were killed in the flood, and Liangzhu people in the north or upstream were able to escape by virtue of their geographical advantages. Among them, the north moved to the Yellow River Basin in China, and the Liangzhu people in the upper reaches moved along the river to today's Sichuan and Sichuan, and gradually merged into their respective cultures.
