What does water mean? The expression "water opposition" was recently derived from.

The reverse direction of water is called "Mercury retrograde". 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.

From the perspective of divination, the phenomenon of going against the water will affect memory, communication, traffic and communication. And it will slow down the progress of related matters, and even detect some obstacles in the process, which makes people feel depressed. Therefore, it gradually evolved into a self-mockery of whether to sail against the current when something happened and you were unlucky. Therefore, this word has become a popular online buzzword.

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.

From the astrological point of view, astrologers usually advise people not to make major decisions and start new projects during the "water retrograde" period, because Mercury retrograde will bring people the opportunity to reflect and review the decisions and plans made in the past, and some better ideas may be incorporated into the plans made earlier, which will make things develop in an unexpected direction.

In addition, astrologers will also emphasize that it is best to back up all kinds of data before Mercury retrograde begins, so as to avoid major mistakes caused by Mercury retrograde energy.

Mercury rules Virgo and Gemini. During the year, Mercury will retrograde once every three to four months, each time lasting about twenty days.
