The Mayan Indians lived in Mexico for thousands of years. The Maya were so bright that they achieved a lot. They had farms, temples and cities with many buildings. They knew much about nature and the world around them. This knowledge helped them to live a better life than most people of that time.

In ancient Mexico there were many small clearings in the forest. In each clearing was a village with fields of crops around it. The Maya planted seeds after they cleared the land. A farmer was able to grow crops that produced for several people. But not every Maya had to be a farmer. Some were builders or priests (祭司).

The Maya believed in many gods. They built large temples to honor them. Skillful workers built cities around these temples. It was difficult because they had to carry all of the building materials themselves. Today, many of these ancient Mayan cities and temples are still standing.

Although the Maya worked hard to build the beautiful cities, very few of them lived in them. Usually, only the priests lived in the cities. The other people lived in small villages in the forests. Their houses were much simpler. Most Maya lived a simple life close to nature.

Measuring time correctly was important to the Maya, so Mayan priests made a system to keep track of time. They wrote numbers as dots ( … ) and bars ( — ). They also made a calendar (日历). The year was divided into 18 months of 20 days each with five days left over.

Around the year 800, the Maya left their villages and beautiful cities, never to return. No one knows why this happened. They may have died from a deadly disease. They may have left because the soil could no longer grow crops. The lost secrets of the Maya are still beyond the reach of modern people. They are still one of our greatest mysteries (神秘).
