Excuse me: What does the sundial mean in traditional astronomy in China? Is it the same as the western concept of the ecliptic? Is it twenty-eight nights on the celestial equator?

I am ashamed to say that the landlord's question taught me a word "Rimo", which I have never heard of before.

Search for relevant information on the Internet and get the following information:

Interpretation of you: 1. Animal tracks? 2. Especially the movement of the sun, moon and stars.

"You, through also. The day is awkward and the month is awkward. " -"Dialect Twelve"

The sundial is naturally the apparent motion of the sun.

For example, "the sun is full of stomach and the moon is clear." How to understand? The stomach lodge is a night of 28 nights, located in the southeast of Aries. Wei means nearby. The first half of the sentence means that the sun has moved to the east of Aries.

Finally, let me talk about my understanding of the landlord's problem. It's just a layman's guess, for reference only.

In today's words, "Japanese ratio" is "the movement of the sun", and classical Chinese pursues the word composed of two words, which is why such a rather uncommon statement is made.

Naturally, the trajectory of the sun's apparent motion is the ecliptic, which is consistent with the western concept, because the definition of the ecliptic is the trajectory of the sun's apparent motion. A passage in the San Zi Jing can be used as evidence: "The ecliptic is called, and the sun shines. Equator, right in the middle. "

There were 28 hotels near the equator 3000 years ago. The equator will change because of the precession of the earth's axis. Now many stars in the 28 th hotel are far from the equator. Equator and ecliptic are two completely different concepts. If you are interested, you may wish to search Baidu for relevant information. It must be much easier to understand than a sundial, hehe.
