What phenology do we observe during the beginning of winter? The ancients believed that there are three seasons for the beginning of winter: the first season is when the water begins to freeze, the second season is when the ground begins to freeze, and the third season is when the pheasant enters a large water and becomes a mirage.
It means that from the beginning of winter, the water surface begins to freeze, which is the beginning of the season.
In five days, it will be the second time, at which point the ground will begin to freeze.
In five days, it will be the third season. During the third season, this pheasant will enter the flood and become a mirage. This is actually an ancient understanding of the natural world, but it may not seem to conform to the principles of biology now. But this is an ancient understanding that this pheasant, also known as a wild chicken, flew into the sea and became a "big shot", a creature on the edge of the sea. This is obviously not the principle we currently understand in biology, but it is the understanding of ancient people.
In summary, there are three seasons for the beginning of winter: the first season, the second season, and the third season. At this time, water begins to freeze and the ground freezes. This is a natural law.
