Do I have to calculate the eight-character arrangement by looking at the sun?

It is necessary to consider the apparent solar time when arranging the astrology. You can think about it. If you don't consider the sun time, it's 8: 00 a.m. Beijing time. If you were born in America, it's night, one day and one night. The horoscope is definitely different. It is also in our country, in the northeast. Now the sun comes out a little after 6 o'clock, but it can't be seen until 8 o'clock in Xinjiang. The time must be different. Therefore, it is necessary to calculate the horoscope with apparent solar time.
