Do you need to use apparent solar time or Beijing time to calculate horoscope?

I think it is more accurate to look at the sun time. For example, some people say that her birth time is 3 o'clock, and 3 o'clock is the time when the ugly girl meets Yin Shi. Inferring numerology according to ugliness or Yin Shi is too different. That's when I knew her birthplace. Born in Dalian, Liaoning Province, there is a difference of more than one hour between Sun Time and Sun Time born in Sichuan. Beijing time is 3 o'clock, so I believe in Sun Time.
