Beibei roams the magical starry world

The time ship took Beibei and his friends to a chariot. A man wearing a crown, luxurious clothes and holding a scepter stood on the chariot.

He was the founder of the first dynasty of ancient Egypt. He unified Upper and Lower Egypt around 3100 BC and became the first pharaoh of Egypt, Menes, also known as Narmer.

“Important events in ancient Egypt during this period:

1. Menes initially unified ancient Egypt and established a slave state.

2. A centralized system began to take shape.

3. The Egyptians created hieroglyphics.

4. The Egyptians have made great achievements in the fields of architecture, sculpture, and painting, such as the pyramids, the Sphinx, etc. "The robot Xiao Cong explained.

The time ship took the friends for a stroll in the Yellow River and Yangtze River basins of China. I saw some men farming in the fields or hunting in the forests. Near some tribes with concentrated populations, women were weaving and some craftsmen were baking. pottery.

In the third millennium BC, Chinese civilization had not yet formed a unified political entity, and development was uneven in various places, but it had entered the late Neolithic Age. "The robot Xiao Cong explained.

The time ship followed a tall man, who was barefoot, wearing a bamboo hat, and striding toward the river with a shovel on his shoulder.

He was followed by a large group of people who worked together to dredge the rivers and dig ditches to lead the water to the sea.

Because he had to finish the project before the rainy season, he never went in every time he passed by his house. Instead, his children waited at the door to see their father coming and going.

After everyone's hard work, the floods were finally controlled, and people were able to return to their homes and carry out agricultural production smoothly.

"Guess who this man is?" the robot Xiao Cong asked.

"It's Dayu who controls the water." The little sage replied.

"The answer is correct. In the next thousand years, China entered the Xia, Shang and Zhou dynasties and the civilizations rose one after another. The residents of the Yellow River Basin developed important cultures such as bronzes and oracle bone inscriptions, and also built large city sites and palaces." Robot Xiao Cong explained.

The time ship followed Dayu. At this time, Dayu was holding a spear and was followed by many soldiers. Today was the day when Dayu led the soldiers to fight the Sanmiao tribe. After the two sides formed their formations, Dayu took the lead and rushed forward. Soon Fighting with the soldiers of the Sanmiao tribe, both sides fought bravely. The people were grateful for Dayu's achievements in controlling floods. More and more people joined Dayu's team, and soon the Sanmiao tribe was defeated.

The people respected Dayu very much and supported him as their king. This established the Xia Dynasty, marking the beginning of the Bronze Age in Chinese history.

The time ship came to the Indus River Basin, and many people in the fields were planting crops such as wheat, barley, cotton, and flax. There are many exquisite pottery, jewelry and textiles in the city, and occasionally some nobles will come to buy them.

The time ship took everyone to the two cities of Mohenjo Daro and Harappa. The two cities are about 400 miles apart and form two cultural centers on the upper and lower reaches of the Indus River.

Mohenjo-daro and Harappa each have an area of ​​about 2.5 square kilometers and a population of about 3 to 4. At the same time, both cities had complete drainage systems, public baths, spacious streets and housing.

"Indus Valley Civilization: The Mohenjodaro Civilization and Harappan Civilization in the Indus Valley began to rise, with developed urban planning, water conservancy projects and pottery making technology." Robot Xiao Cong explained

The time ship visited present-day countries such as Mexico, Guatemala, Honduras, El Salvador, Nicaragua, Costa Rica, and Panama, and saw hieroglyphics and the upcoming Mayan civilization. Since we needed to learn more about the Mayan civilization later, the time ship did not go in depth. .

"Civilizations in Central America, mainly the Mayan civilization, began to rise. Developed astronomical observation, mathematics and architectural technology, as well as important cultures such as hieroglyphics." Robot Xiao Cong explained.

Beibei was the first to say: "I feel that human civilization is developing faster and faster."

"Yes, I also found that the changes are getting faster and faster. Are you guiding and participating? Especially the construction of the pyramids and various miracles." Dantan asked

"We did not participate in the pyramids. We do not want to change the history of human society. However, when large-scale plagues, floods, droughts, earthquakes, etc. occurred out of humanitarianism, our aircraft changed its image to help, so some legends appeared in mankind." The little robot Cong said

"I found that this stage is the emergence of kingship, cities and writing, which is the key to promoting social development." Xiaohui said

"In order to maintain royal rule, emperors and dignitaries established cities and carried out centralized management. People needed a better life, which created demands and formed a social division of labor. The nobles needed a stable continuation of their status, and writing developed." Jack added.
