Are there earthworms in February of the lunar calendar?

On the second day of the second month of the lunar calendar, there is a folk saying that "on the second day of February, the dragon looks up". Why did the dragon look up on February 2?

This folk custom is related to festivals. Around the first day of February, it was a "shock". Many animals, such as frogs, snakes, earthworms, etc., go into hibernation in winter, which is called "entering the sting". Around February of the following year, the weather turned warmer, and some insects gradually ended their hibernation and began to go out. It seems to be awakened from sleep by bright spring days or deafening spring thunder, so this festival is called "Jing Zhe".

The legendary dragon was imagined by our ancestors on the basis of snakes, earthworms and so on. So people also call this snake "Little Dragon". Around February 2, snakes, earthworms, etc. End hibernation and start activities. Folk believe that the dragon is a symbol of the son of heaven, an auspicious thing, and the master of storms, and "February 2" is the day when the dragon will ascend to heaven and start activities, so it is called "February 2, when the dragon looks up".

So, why not "February 1st" or "February 3rd"? This is related to our love of even numbers in folk customs.

In ancient China, especially before the Qin and Han Dynasties, all the "heavy days" such as January 1st, February 2nd and March 3rd were regarded as the days when heaven and earth were connected with each other. Therefore, on such days, people need to do more prayers, sacrifices or commemorative activities to achieve happiness, well-being and good luck.
