There is Yu's tile coffin. - "The Book of Rites"
Anyone who has an urn coffin burial custom can be determined to be a descendant of the Yu family.
Youyu has writing, and there were highly mature scripts 11,000 years ago, which have been found in the Shangshan culture in the lower reaches of the Yangtze River.
Wherever there is a Yu urn coffin, it must be accompanied by Yu's words.
Youyu continued to migrate later, leaving a large number of urn coffins in Xi'an Banpo six or seven thousand years ago, and a large number of urn coffins of Yangshao culture prove that this is the culture created by Youyu.
Of course, Yangshao culture also has words.
This is the Youyu script of the Banpo culture.
This is the Youyu pottery inscription of the Jiangzhai site.
The Youyu people, who created the Yangshao culture, continued to migrate westward and created the Majiayao culture five thousand years ago.
This is the word "Wu" of Majiayao Youyu, which is exactly the same as the word "Wu" in the oracle bone inscription.
This is the "swastika" character of Majiayao Youyu's family, which is exactly the same as the "swastika" character in the oracle bone inscription.
About 5,000 years ago, a group of Youyu clan came to the southwest of the mainland, and together with the Xia Hou clan who came here more than 3,000 years ago, they became the common ancestor of today's Naxi and Yi people.
The Naxi people also practice urn burial, and they are cremated in a coffin before being buried in an urn coffin. It is 100% descendant of the Yu clan.
This is the urn coffin burial of the Naxi people.
In 1933, after Fang Guoyu inspected the Shuhe tombs of the Naxi people in Lijiang, he recorded in the "Examination of the Tombs of the Ming Shiheyuan" that two large clay pots were dug up, and there were six small clay pots distributed next to them, and the clay pots contained ashes and blocks.
Of course, the Naxi people have a written language, and like the ancient Yi script, it has been handed down since 11,000 years ago.
These characters look like this, they are living hieroglyphs.
The same wave of Youyu people arrived in Egypt 5,500 years ago, leaving behind hundreds of urn coffins.
There is an urn coffin left by the Yu clan in Egypt
Of course, there was also writing in ancient Egypt, which was brought by the Yu clan, which is almost exactly the same as the script still used by the Naxi people today.
In contrast, as long as you are not blind, as long as you are not stupid, you can come up with the right answer.
Ancient Egypt had the Yu script
