Watching the sky at night is an ancient astrological term. The so-called astronomical phenomena refer to some phenomena that occur outside the earth's atmosphere-astronomical phenomena, such as the collision of planets, the profit and loss of the moon, the looming of comets, the appearance and appearance of the sun, the fleeting meteor, the outbreak of new stars, the solar eclipse, the aurora and other changes in the operation of celestial bodies.

Explain in detail:

Ancient ancients often used divination as the basis of good or bad luck. Astrology, like Taiji, Hetu, Luoshu, Zhouyi and Bagua in essence, originated from prehistoric civilization. And some people who are proficient in this research often make predictions by observing the astronomical phenomena. Some people use astrology to change dynasties.

For example, Zhuge Liang was mentioned many times in the Three Kingdoms to observe the celestial phenomena at night. When Zhuge Liang just came out of the mountain, he once said to Liu Beiyan: Watch the sky at night, Liu Biao will die soon, and Jingzhou will be the general in the future. The night before Zhuge Liang died, he was very scared after watching the sky at night and said to Jiang Wei around him, My life is almost over! It can be seen that the skill of watching the sky at night does have its mystery.
