What do you mean, water flows backwards and dissipates?

The reverse side of water means that everything is scattered, which means bad luck.

The complete statement of water inversion 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.

The origin of water inversion in astronomy;

Mercury's orbit is closer to the sun than the earth, so it only takes 88 days to go around the sun, while the earth is far from the sun, and it takes 365 days to go around the sun. It's like two people running on different runways Mercury runs fast in the inner circle, while the earth runs slowly in the outer circle. Before catching up with the earth, mercury moves forward; After catching up, it looked like running backwards and turned into retrograde.

But in fact, mercury has been moving forward, not retrograde. The reason for the illusion is that we regard the earth as a reference. If the sun is taken as the reference, there is no so-called mercury retrograde.
