The Winter Solstice and Chinese Astrology

Yesterday was the winter solstice, while modern society no longer maintain many ancient customs, but some of my friends still go to dinner with their parents. In chinese astrology, the winter solstice is a very important turning point, from this day, Yang began to grow, Yin gradually decline. When the winter solstice, 4 Pillars of Destiny and Da Liu Ren’s horoscope must change, but the Purple Star Astrology birth chart is not affected, because it is based on the moon as the core of the horoscope system.
