What does waterproof reverse mean?

The waterproof reverse symbol is a symbol to prevent discomfort caused by mercury retrograde, which is the same as the disaster prevention symbol and disease prevention symbol.

Here, spells are used by Taoism and divination, claiming to have many functions such as exorcising ghosts and gods.

Mercury retrograde means that mercury orbits 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 retrograde. During the year, Mercury will retrograde once every three to four months, each time lasting about twenty days. ?

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.
