What stars are abnormal when the world is in chaos?

The stars are abnormal, and the ancients often associated them with the turmoil in the world. There are many astrological phenomena, such as the appearance of comets. Common ones are Mars staying in Antares, Ying Ying entering Nandou and Taibai entering the moon. Most of them are related to Venus and Mars.

Astrology in the military world is a fine and rigorous discipline, and the specific signs of astronomical phenomena need to be very subtle, rather than simply explaining whether the world is peaceful or not. The main idea of China in ancient times was that the sky hung like a warning sign. Generally, auspicious phenomena often appear when politics needs auspicious omen, and warning signs are more unlucky. That is, the astronomical phenomena used for divination are outside the sun, the moon, five stars and many stars, and they are the gas of miscellaneous stars.
