1 is related to "weather phenology". The introduction to astronomy in the book "Huainanzi" of the Western Han Dynasty states that "on the fifteenth day after the spring equinox, when Dou Zhi Yi is on his back, the Qingming wind will arrive." , so it is called Qingming.”
2 Although there are slight differences in the text descriptions in these two classics, they actually say the same thing, that is, "all things present a clean and bright phenomenon and feeling"
3. From the seasons understand it from a perspective. Qingming Festival is the fifth solar term among the 24 solar terms. At this time of year, the sun has crossed the equator for two weeks (the sun shines directly on the equator during the vernal equinox), and the sunshine in the northern hemisphere is gradually lengthening, with longer days and shorter nights.
After the beginning of spring, after the three solar terms of rain, the Waking of Insects, and the Vernal Equinox, the cold air hidden deep inside the earth in the harsh winter is being extracted from the surface of the earth bit by bit by the warmth brought by the sun, and is completely lost.
At this time, the spring flowers are blooming, the earth is covered with thick green, the sky is clear, the air is fresh, and everything is growing in time and flourishing. It can be described as "clean and upright" and "thriving".
4. Understand from a humanistic perspective. "Qing": The sky is light and clear and rising. God is clear but not turbid, transparent and bright; God is clear but selfless, and is kind to all things. "Ming": Being knowledgeable about affairs and following the trend is called Ming.
The ancients used the word "Qingming" to declare that future generations should be honest and upright, do things clearly, and be "upright and honest".
During the Qingming Festival, we worship ancestors, communicate with ancestors, and let them judge whether what we do in the world is honest and upright. As the old saying goes: People are doing it, God is watching.
Heaven includes ancestors. The ancestors only bless those descendants who are honest and upright and do things clearly. Therefore, I would like to warn future generations to always be vigilant, work diligently, and be alert at all times, as if walking on thin ice or facing an abyss. We have been established with virtue and strict discipline.
