What is the significance of the Millennium?

The Millennium refers to the water droplets formed by the condensation of water vapor on the ground or near-earth objects after the weather turns cold and the temperature drops. For example, vegetation will be covered with dew in the morning.

During the white dew, the summer monsoon is gradually replaced by the winter monsoon, and the cold air changes from defense to attack. In addition, when the direct point of the sun moves south, the sunshine time in the northern hemisphere becomes shorter, the light intensity weakens, and the ground radiation dissipates heat quickly, so the cooling speed gradually accelerates. The Millennium basically ended the sweltering heat in summer, and the weather gradually turned cold, and the cold gave birth to dew condensation. The ancients used four seasons to match five elements. Autumn belongs to gold, gold and white alternate with each other, and autumn dew is described in white, hence the name "White Dew".

Waiting for Hongyan to come: After the White Dew, migratory birds that are most sensitive to climate migrate collectively. Hongyan began to fly from the north to the south.

Second, wait for the mysterious bird to return: the mysterious bird refers to the swallow, and the swallow will fly to the south for the winter.

Three migratory birds raise shame: this "shame" is as delicious as "embarrassment" Raising shame means that birds perceive cold air and store food for the winter.
