In ancient times, it was first used as the sun to represent our own time. It is said that the ancients were very smart, and from our country, it can be seen that there are some real things about the four great inventions in ancient China, so it is conceivable that he was very developed at that time, and in the earliest ancient times, we generally used to keep time, generally using the sun, the ancients have always said, 12 hours, then for us now, 12 hours is equivalent to an hour, that is, two hours, <>

And they can use this method as our time with Zi Chou Yinmao, and so on as some tools for ancient timekeeping, so it can be seen that it was very smart at that time, especially in the Western Zhou Dynasty, so these are all historical basis to prove this thing, and in ancient China, in the Warring States period, the application of mechanical principles is mainly divided into two categories, the first is to use fluid mechanics is the second is to use mechanical transmission in some timely, For example, the first one will use killing or something else, <>

In the second one, you can use the burning sky or the god to operate in time, remember that the time is accurate, and there is no time to make a mistake? Another is that some of our modern people use clocks and watches, and there is a sign that is particularly good-looking for some of our current boys, so this is also very powerful, and then a current time, for us, everyone is very important, especially a person, with a certain concept of time, I think it is very regular in life or life and study, <>

I think such people are very serious in their work. So I think our country has been a very strong since ancient times, and it is a very wise group, although in the 19th century and 10s of the last century, we closed off the country, we gradually began to lag behind, but now we have come up step by step, and to the forefront of the world, I think this is a very good achievement.

In ancient times, the earliest time was calculated by the copper kettle dripping, and there was the sundial, which could also accurately calculate the time, and the general poor people listened to the rooster crow to judge the time.

The time is represented by 12 earthly branches. This representation is still very accurate, and it corresponds to the current time.
