Understanding this article, the sea of stars will no longer be mysterious, at least it will allow you to answer the following problems with your eyes closed in seconds, and it will be accurate.
Question Type 1: Known a certain year, a certain month, a certain day, a certain time, regardless of rain, rain and snow, which star or constellation is the southern middle sky? For example, at 15:00 on April 6, 2025 AD, what is the passing of Nanzhongtian? Answer: Biju, Taurus.
Question 2: It is known that a certain accommodation passed through The South Zhongtian at a certain time, what day is it? For example, at 19:00 on a certain day, Kui Su passed through Nanzhongtian, what year, month and day? A: Every year around December 22.
How was this derived? Yi Chen spoke directly.
Step 1: Remember the twenty-four solar terms and the twenty-eight stars in order. This is the cosmic-level space-time coordinates left to us by our ancestors, which have been tested for a long time, remembered for a lifetime, and benefited for life.
Why in order? Just like a person has three anxieties, he must first loosen his clothes, then adjust his posture, and then defecate. First come, first served, and the order cannot be reversed.
Twenty-four solar terms: spring rain shocks the spring valley days, summer is full of mango and summer and summer are connected, autumn dew and autumn frost falls, winter snow and snow are small and cold in winter.
The time of the intercourse of each solar term, every year in those two or three days, the millennium unchanged, this is the transmission point of the time and space transformation, should be known.
Twenty-Eight Stars: Western Seven-SuKu Kui-su, Lou Su, Stomach Su, Pleiades, Bi-Su, Qi-su and Betelgeuse; Southern Seven-Sus Well-Su, Ghost-Su, Willow-Su, Hoshi-su, Zhang-su, Wing-su and Yi-su; Eastern Seven-Su Kaku-su, Kang-su, Honjuku, Fang-su, Heart-Su, Tail-Su and Ji-su; Northern Seven-Su Dou-su, Niu-su, Female-Su, 虛宿, Dangerous Su, Room-Su and Wall-Su.
Each star or constellation has fixed coordinates on the celestial sphere, almost equally divided into the entire ecliptic 360°. Inferred from them, can the stars up and down and left and right still run away?
For example, the fork that is pushed to Bilju is equivalent to grabbing the double horns of Taurus; seeing the double horizontal of Theo is equivalent to stepping on Gemini's feet; looking at the horn is equivalent to hugging the big long legs of Virgo; and the tail is directly the tail of Scorpio.
Step 2: Modeling. Tie the time, the solar terms and the stars to the stars, and enter the seat with the number, see one know three. Available on any date, at any time and any place.
For example, every year around summer day, everywhere midnight at midnight, the south middle sky will see the krypton, the noon 12 o'clock south middle sky must be the stomach stay, 18:00 south middle sky to see the willow house, 06:00 south middle sky to see the female accommodation.

The same is true of other solar terms and dates, because the orbits of the sun and the earth and the relative positions of the stars have changed very little over hundreds of years (according to the dust deduction, each house has only shifted 1h in 1200 years), so the modeling is shown below.
Prototype diagram of time, solar terms and astrological coordinates
Model diagram: the center is the sun, the blue earth rotates and rotates around it; the black number is a 24-hour clock, the number head is bound to the twenty-four solar terms, and the outer of the solar circle is the star bound to it, indicating the cosmic starry sky; the small red number outside the black circle is the celestial red meridian, indicating the red meridian coordinates of each celestial ball, not fully marked, and the red meridian = clock + 6.
Step 3: Derivation, divided into four small steps.
1, see one know three. Memorize the knotted star tips, that is, the knots that bind the solar terms to the stars, and make a few strokes of the line on the model diagram to help understand.
The purpose is to give a solar term or star, and to immediately think of the other three solar terms and stars that cross vertically with it.

The water is in danger, full of snow; the snow is full of mangled tails, and the white room is terrified.

2. Meridian morning and dusk. The meridian and the morning and evening lines cross, defining the astrological and solar terms corresponding to 06:00, 12:00, 18:00, and 24:00 of the day.
3. The stars are seated. For example, I want to deduce the position and time of each star in the sky during the Qingming Festival.
Qingming Festival is the "Qing" in the Star Festival recipe "Hankui Qingjiao, Xiaojing Xiaodou". Its binding is the corner su, the horn su into the sub-circle of the above figure, indicating that the night 24:00 the corner su is located in the south of the sky, and the cold dew opposite the Qingming is naturally "noon (Kui Su)", indicating that the day 12:00 South Zhongtian is Kui Su, the same reason to arrange "morning (Dou Su)", "dusk (jing su)" one by one into the seat, that is, the following picture.
4. Make up for the time stay. The previous step is just to complete the big frame, clockwise to make up the time and stars.

There are no solar terms to arrange for the Pleiades, the Stars, the Houses, and the Void Four Houses, and their actual positions are also squeezed between the front and back houses.
Combined with model diagrams and more practice, it is inevitable that practice will make perfect. Once you're done, you can know which stars are above your head whenever and wherever you close your eyes. In turn, looking at the stars overhead can also know when and where you are.
