Did the ancient people know the shape of the earth?

The ancients actually knew the shape of the earth, but their study of astronomy and geography was not as precise as it is now. In ancient times, there was a doctrine called the doctrine of the circle of heaven and the earth, which is a manifestation of the doctrine of yin and yang, and the essence is that the sky is round and the earth is square.

1. From the Book of Changes, the Yellow Emperor's Neijing and the Hetuluo book, we can prove that the doctrine of the round sky has always existed, and it contains a simple cosmology. According to the theory of yin and yang, the beginning of the chaos of heaven and earth is called Taiji, and Taiji gives birth to two instruments, dividing yin and yang, and there is heaven and earth. The ancients would call the universe composed of many stars the heavens, and the earth that stands on the ground and supports it.

Because the sun, moon and stars move in cycles and circles, like a closed circle, it is commonly known as the circle of the heavens, while the earth is always still and carries all things, just like a square object, so it is called a place.

2. The characteristics and connotation of the round heaven and the earth are a manifestation of the yin and yang theory. The circle of heaven is the understanding of the universe, the place refers to the coordinate system of all directions of the earth's plane, and the square refers to the direction, for example, the sub represents the north, the noon represents the south, and the ancients would use twelve earthly branches, ten heavenly stems, and four hexagrams to represent the twenty-four directions respectively, and constitute the entire circumference.

3. The Significance of the Round Heavens and the Origin of the Doctrine of the Round Places proves that there was a dialectical study of astronomy and geography in ancient China. This is the way of thinking of the ancients in understanding the world, and the social practice of thousands of years has proved the correctness of this theory. Although not as precise and extensive as current research, it is also a major way of understanding the universe.

Through the perception of ordinary people's five senses, they achieve verification, so as to discover the laws of the universe.

The theory of the round heaven is also a philosophical thought, which also has a profound impact on traditional Chinese culture, and many traditional customs and people's living habits are inseparable from this theory, such as the feng shui problem of architecture. Dear readers, do you understand?

I don't know, the most common saying in ancient China is that the sky is round and the earth is round, and people think that the earth is square, which shows that they are very ignorant.

The ancients did not know the shape of the earth because they had not seen the shape of the earth, and all speculations about the earth were inaccurate, some people believed that the sky was round and the earth was square.

In fact, ancient people did not know the shape of the earth, and it can be seen from various theories that the earth is round, and the ancient people have always believed that the earth is flat, not round as we know it now.

In ancient times, due to the underdevelopment of ancient science and technology, the level of science and technology limited the degree of cognition, and the ancients could only intuitively understand the earth by observing the phenomena.

The ancients did not have enough science and technology at that time, and did not know the actual shape of the earth, so they all thought that the earth was square

It's a speculation, after all, there is no way to actually detect it without the current technology.
