What are the three phases of cold dew solar terms? What are the three stages of Hanlu Festival?

1, cold dew three times: Hongyan guest, birds entering the water as clams, chrysanthemums with yellow flowers.

2. Wait a minute: Red Rock Guest. The geese zigzagged south. Hongyan is probably the most common phenology among the 24 solar terms. The ancients in China had many feelings for the geese. Whether it's Li Bai's "geese attract sorrow, mountains hold the good moon" or Du Fu's "geese are hard to send and dreams are hard to make", all of which are the best explanations for the ancients to attach importance to geese. During the cold dew season, it was precisely the last batch of geese that moved south in a big way, and the geese came to the south as guests. The ancients paid close attention and were always ready to do their duty as guests.

3. Second class: A sparrow enters the water as a clam. In the cold late autumn, all the birds disappeared. The ancients saw that many clams suddenly appeared on the seashore, and the stripes and colors of shells were very similar to those of birds, so they thought clams belonged to birds. Of course, it is nonsense that birds turn into clams, but it implies the ancient people's understanding of heaven and earth. They think that at this time, the yin and qi of heaven and earth are heavy, and the scattered things naturally become artifacts. If birds are still active, it means that the season is out of order and there will be disaster.

4, third class: chrysanthemum has yellow flowers. That is to say, chrysanthemums usually open at this time. Everything in the world is negative and yang is embraced. When the yang is getting stronger, everything will sprout, sprout and blossom. Only chrysanthemums will bloom when the yin is getting heavier and heavier. At this time, yin flourishes and yang declines. Chrysanthemums don't bloom, which means that there is not enough yin, and even the land can't be cultivated. Because of this feature, chrysanthemum has been endowed with many unique connotations. For example, it is one of the four gentlemen of Mei Lan, and Zhu Ju and Chrysanthemum have experienced storms and become symbols of noble personality. Tao Yuanming once wrote the poem "Picking chrysanthemums under the hedge and seeing Nanshan leisurely".
