Is it accurate to calculate horoscope solar time or flat solar time?

There were no clocks and watches in ancient times, and there was no so-called unified time in Beijing. Put a branch on the ground and look at the shadow to see the time.

Different regions are definitely different. So the theory of apparent solar time is very convincing. It's just that now the older generation of numerologists don't have to look at the solar time.

They have been using the previous four-column method, which is also very accurate. So it really depends on the level of the individual. Just from different angles, each has its own version.
