Understand that the sun and the moon shine together

The understanding of the sun and the moon is scientific understanding, cultural implication and practical application.

First, scientific understanding:

Sunrise is an astronomical phenomenon, which is mainly caused by the different orbital periods of the earth moving around the sun and the moon moving around the earth. This phenomenon usually occurs from the fifth day to the eleventh day of the fifth lunar month. At this time, the moon and the sun may be in the same direction in the sky, with clear weather and high visibility, which is relatively easy to observe.

Second, the cultural implication:

In the traditional culture of China, it is not only a common idiom, but also has profound symbolic significance. It symbolizes harmony and unity, because although the sun and the moon are two celestial bodies with completely different properties, they can appear at the same time and reflect each other under certain conditions. In addition, the sun and the moon are also used to describe the harmonious coexistence and mutual illumination of things.

Third, the practical application:

In daily life, the concepts of the sun and the moon can also be used to inspire people's understanding of values such as harmony, unity, mutual assistance and hope. For example, artists may express these themes by depicting the scene where the sun and the moon shine together, educators will use this phenomenon to educate students to cherish the importance of unity and cooperation, and managers may get inspiration from it to establish a more harmonious working environment.

Brief introduction and appearance time of the sun and moon;

1, Introduction to Sun and Moon, Happiness of Sun and Moon

Sunrise is a natural phenomenon, which is caused by the different rotation periods of the earth around the sun and the moon around the earth. Direct observation of the sun, moon and sky with naked eyes requires certain conditions. Generally, it can only be seen in broad daylight when the sky is clear and the visibility is good from February/Kloc-0 to March in the autumn lunar calendar.

2. Time of appearance

The sun and the moon are just a natural phenomenon, which requires the sun and the moon to be above the horizon at the same time. Theoretically, as long as the atmospheric conditions are good, this phenomenon may occur except the fifteenth day of the lunar calendar.

But there is a second condition, that is, the limit magnitude of the sky (the darkest celestial body that can be seen) cannot be too low, so generally speaking, when the sun rises or is about to set, the brightness of the sky can easily meet this condition (even in cities).

So in the first half of the lunar calendar (after the fourth day of the lunar calendar), you can see the moon phase when the sun goes down, from west to east in turn. In the second half of the lunar calendar (before the 27th), you can also see the moon after the sun rises, from the western sky to the eastern sky.
