What does constellation inversion mean?

Simply put, Mercury goes around the sun like the Earth, but when the orbit direction of Mercury is different from that of the Earth, seeing Mercury on the Earth will produce the visual effect that Mercury is retrogressive. During the year, Mercury will retrograde once every three to four months, each time lasting about twenty days.

Mercury retrograde is not the reversal of the actual running direction of mercury, but the change of visual trajectory caused by the difference of ecliptic angle between mercury's running orbit and the earth's rotation.

Mercury retrograde is often called "water retrograde" in astrology. In divination, it is said that the negative side of water affects memory, communication, traffic and communication. This will bring everything wrong and make people feel depressed.
