Shao Yong's Observing Things, the Solstice of Half a Winter.

Half of the winter solstice "The winter solstice in a year is like midnight in a day, that is, twelve o'clock at night. Everything is quiet, but it is ready. " This so-called "darkness before dawn".

The heavenly heart has not changed: heaven and earth are ruthless, why do you have a heart? Confucius' so-called heart of heaven and earth refers to the natural law of ups and downs. In the sixty-four hexagrams, he lamented that everything was very cold, even colder, because of the climate characteristics of winter solstice, but things were changing quietly.

When the sun first moves, everything is not born: refer to the above understanding.

This is a poem by Shao Yong, explaining the Book of Changes.

I hope I can help you, and I hope to adopt it!
