Interpretation of Zhu Meihua's first blossom in Xiaohan.

In addition to "72 hours", the ancients also summed up "24 hours in Hua Xinfeng". It refers to the 24 hours from "slight cold" to "Grain Rain", which represents the time when flowers bloom. The wind blowing during the flowering period is called "Hua Xinfeng". The three kinds of "Hua Xinfeng" in "slight cold" are plum blossom, camellia and daffodil. In other words, with the geese flying northward, plum blossoms on the earth are also trying to open up in the "slight cold" solar terms. Therefore, Zhu, a poet in the Song Dynasty, said: "The yellow bell is rhythmic, the wind rises, the yin rises and the yang rises." Sunflower shadows will move to the sun, and plum blossoms will bloom before the slight cold.
