Are the "yin" and "yang" of the mountain south or north respectively? What about water? Why?

There is a shadow to the north of the mountain. The water in the south of the mountain is yang in the north, and the water in the south of the mountain is yin.

The sun is in our south, so it shines from south to north. Because the mountain stands on the ground, the sun shines on the mountain, first in the south of the mountain. Because there is sunshine in the south, the south of the mountain is sunny, and the north is facing the sun, so it is cloudy without sunshine. On the other hand, the river is underground.

The reason why the mountains are sunny in the south and cloudy in the south.

The relevance of the earth's rotation: the deflection of objects moving horizontally along the surface.

The rotation of the earth will also cause objects moving horizontally in any direction on the earth to deviate from the original direction. Based on the moving direction of the moving object, the horizontal object in the northern hemisphere leans to the right and the southern hemisphere leans to the left.

The reason why horizontal objects deflect on the surface is that all objects have inertia and try to keep their own speed and direction. As mentioned above, the horizontal direction on the earth is based on latitude and longitude, the longitudinal direction is the north-south direction and the latitude direction is the east-west direction.

However, due to the rotation of the earth, the latitude and longitude, as the standard of north-south and east-west directions, deviated with the autobiography of the earth. Therefore, the horizontal motion of objects that really keep the same direction, if represented by the direction on the earth, is relatively deflected.
