"Yin and Yang" is a group of evil spirits in the four-pillar numerology. It is basically okay to see the same horoscope in one group. There are many taboos. It generally refers to an unhappy marriage, usually second or multiple marriages. However, Shensha is only a reference in numerology, and the specific combination of horoscopes must be combined to make a conclusion. It is inaccurate to rely solely on Shensha.
