Which poem describes the characteristics of the slight cold solar terms?

The poem describing the characteristics of the slight cold solar terms is a new nest of happy magpies.

Han Xiaolu, a happy magpie building a new nest, symbolizes the arrival of solar terms, just like "Da Lu" in the melody, which causes the rhythm between heaven and earth, and magpies begin to build nests happily at this time. This poem comes from Tang Yuanzhen's poem "Twenty-four Qi, Slight Cold December Festival". ?

In the slight cold phenology, the ancients summarized three phenomena: geese began to fly north, magpies began to nest, and pheasants began to crow. This is a sign that spring is coming. These birds are more alert than humans. ? There is a folk saying: "A slight cold is better than a severe cold", which means that the sun's qi rises during a severe cold, but there is no slight cold. In other words, in the 24 solar terms, slight cold is the coldest. ?
