Their graves contain items in their lives (they can tell you that they live in the grave). You can judge whether they are rich or poor by the way they fill their graves (they may put what they like in the place they live)
The ancient civilizations of Egypt and China are very similar. The government of these two places has been established, and the geographical position of China is very similar to that of Egypt. Religion is also a common feature of these two civilizations. Strangely, given the fact that the two cultures are separated, they have many common features.
In the early history of China, the geographical location of China isolated outsiders, few people were in and out of this area. China's steep mountains, the natural boundaries of the sea and the sea protect the ancient Chinese culture. It is primarily a barren desert, with Egypt's geographical location also isolating it a bit, as there are narrow green lush fertile land on both sides of the Nile River and the Delta. There is also the sea on one side. But Nile enables the Egyptians to trade with other cultures, and ultimately the invaders go into the Egypt from the ocean.
The geographical factors in China influenced the development of Chinese early civilization. The best settlement is near Yangtze River and Yellow River. These areas are very fertile and offer a lot of food for the people who live there. There are plenty of fresh water. Also, the river is a means of transportation. These factors have contributed to the formation of villages in these fields. Other areas in China are not well suited for reconciliation, and in many cases serve as a buffer point in China. The Himalayas are the highest mountain in the world, not a place to calm down. Desert areas in China, including the Gobi Desert and the Taklimakan Desert, are not easy to settled. Therefore, most of the settlements in China are near Yellow River and Yangtze River.
