For the universe, the time interval between ancient and modern human beings is almost incalculable, so there is no comparison between ancient and modern stars. In ancient times, there was less pollution and the sky was more visible, so it may be more visible than now, but it does not mean that there were more stars in ancient times than now.

In ancient times, there was no light pollution like it is now, and even in the most prosperous palaces, you can see the stars.
There is a poem "The night is as cool as water, lying down and watching the morning glory Vega." It can be seen that even in the palace, you can see the Cowherd and the Weaver Girl, and the Milky Way hangs horizontally.
Today's cities can no longer see the starry sky, and for some urban people, the starry sky is an abnormal phenomenon. While we are grateful for the convenience that urbanization has brought us, shouldn't we also think about what it has taken away from us?

I don't know what you mean by whether there are many stars that can be seen or the total number of stars, if you say that there are many stars that can be seen, it must be more than now, there was no industry that polluted the air in ancient times, and there was no serious light pollution like now, even in the bustling "urban area", a look up is full of stars.
If we talk about the total number of stars, then this total number is changing all the time, some stars have just died, and some stars have just been born.
I don't know if it will help you

It should be similar to the current one, I feel that there were more in ancient times, because of the current air pollution, which caused the number of stars to decrease!
-
Light pollution and how many stars are there Why is it a problem! I'm struggling with this.
It's basically the same, but it's actually that the total number of stars changes every moment, because the universe is so big, there are stars dying and stars being born all the time, and it's just that when there are more dead than new, and there may be more new than dead, but it's basically the same!

Bright Tears, Nameless Pearl, Xinghan, Tianhan, Xinghe, Tianhe and Yinwan, etc. Whether ancient or modern, stars refer to celestial bodies that can be seen with the naked eye, and can be divided into white dwarfs, comets, planets, and planets in terms of types.
The brightness of the stars is also different when viewed to the naked eye, with some stars having relatively high brightness and some stars having relatively low brightness. In many cases, the brightness of the star will be restricted in two aspects, the first aspect is related to the ability of the star itself to emit light, the stronger the star's own luminous ability, the greater the brightness; The second aspect has to do with the distance of the stars from the Earth, and the closer they are to the Earth, the brighter the stars will be.
In the planetary realm, the brightest star is Venus, which can travel at a speed of about 240 kilometers per hour.

In ancient China, people believed that the sky was round and the earth was very respectful. The emperors of the past dynasties believed that they were the Son of Heaven and governed the country according to the mandate of Heaven, and they also attached great importance to the changes in the heavens. China is one of the earliest countries in the world where astronomy started, and people in primitive societies would observe celestial phenomena.
During the reign of Emperor Yao, astronomical officials were set up to specialize in "observing and teaching time".
Henan Dengfeng Stargazing Observatory is the oldest existing stargazing platform in China, which was built by Guo Shoujing in 1279 and has a history of more than 700 years. This ancient stargazing platform is about 10 meters high, and the building is large and small, and consists of a stone gyu and a high platform. Beams are set on the high platform, and the ancients calculated the spring equinox, summer solstice, autumn equinox, winter solstice and other seasons according to the projection length of the beam on the stone gui.
The rulers of the Yuan Dynasty believed that the heavens were supreme and attached great importance to astronomy. After Kublai Khan ascended the throne, he set up Si Tiantai in Shangdu, and after moving the capital to Dadu, he recruited talents to set up the Taishi Academy, and later built stargazing platforms all over the country. The best astronomers of the Yuan Dynasty were Wang Sui and Guo Shoujing.
Together, they completed the "Chronological Calendar", which differed from the modern calendar by only 26 seconds a year, and Guo Shoujing successively created and improved more than 10 kinds of astronomical instruments, such as the simple instrument, the high table, and the upward instrument.
