What is a Chinese birth chart?
A Chinese astrological chart restores a synthetic and principled representation of the deep nature of an individual. This science of being comes from the metaphysical doctrine of Unity of the Far Eastern tradition called Taoism. It considers the luminaries (the Stars) not as agents of influence but as indicators marking out the rhythms of the diversity of the modalities constituting Universal cohesion.
It distinguishes between three types of luminaries, those constituting the stellar background embodying through their mutual immobility the immutability of the Principles, those having relatively erratic movements compared to the constellations embodying the changing movements of feelings, finally the two complementary luminaries the Sun and the Moon embodying Active Perfection and Passive Perfection respectively, which are then broken down into two principles Yang and Yin.
An individual being is seen as a particular movement and a distinct self proceeding from a sort of intelligible and discernible aggregation of constituent elements marking a provisional intersection between two universes with their own rhythms, namely the Macrocosm and the Microcosm.
Chinese Astrology is based on a luni-solar calendar and uses the 7 stars of the constellation Boisseau (Teou corresponding to the Big Dipper) as a cosmic reference clock.
The Tu Vi software is based on the calculations and principles given by Vo Van Em & François Villée in their book “The True Chinese Astrology” from Editions Traditionnelles. The positioning of the stars follows the method of Mr Nguyen Ngoc Rao.
