Which fortune teller is accurate when the sun is shining in Beijing?

Hello!

1, at eight o'clock, solar time is the standard, that is, local time is the standard. China spans several time zones, so it is obviously impossible to use Beijing time to arrange eight characters.

Now the clock is used, and the local time can be converted into 4 minutes per longitude (why? Please read books about astronomy), the formula is as follows:

Local (depending on solar time) hours = 23 4 (Z-J)/60 (hours) Beijing time.

Among them,-plus sign or minus sign is used in the eastern hemisphere, while-sign is used in the western hemisphere, because the longitude of east and west increases in opposite directions;

J- local longitude;

Z- the central longitude of the time zone. China uses Beijing time uniformly. Beijing is located in the East 8 time zone, and the central longitude is East longitude 120 degrees (Nanjing Purple Mountain Observatory), so z is replaced by 120:

Local (solar time) sub-hour = Beijing time 23 4 (120-J)/60 (hours).

For example, find out the time difference between apparent solar time and Beijing in Tianshui City, Gansu Province.

Solution: From the map or Gogu Earth, Tianshui City, Gansu Province is on the line of east longitude 105 degrees, that is, J = 105 degrees, and substitute the above formula:

Tianshui City, Gansu Province, Zishi = 23+4 (120-105)/60

=23+ 4× 15/60

=23+ 1

=24 hours

In other words, it's 23 o'clock in Beijing, but it's 24 o'clock in Tianshui City, Gansu Province, one hour later than Beijing. And so on: Beijing 9: 00- 1 1, Tianshui City, Gansu Province 10- 12.

It is very convenient to find out the local longitude number and substitute it into the above formula when looking at the sun.

2. "There are water outlets on the left and right sides in front of a house in Feng Shui. Should it be left or right? " Both sides count, and they are not connected.

3. The direction is broken by the stars, and the mountain side is broken by the stars. If Zishan is at noon, Kungong is at the court, and Shanxing is singing in Kungong, generally, profit and loss are not counted, and the palace is in the mountain, regardless of wealth.
