Understanding of the sentence "The Analects of Confucius is cold at the age of eight" Who knew that there were eight in the Analects of Confucius in the sixth grade?

"The Analects of Confucius Zi Han" says: "When you are old and cold, you will know how to carve pine and cypress." Cold weather is the coldest time of the year. Carving, through "withering", withering. Every year when the weather is coldest, I know that most other plants are dying, and only pine and cypress are tall and straight. Metaphorically, a moral person has tenacious strength, can endure hardships, can endure torture, and will not change his initial heart.

Deep meaning: cold year: a metaphor for dirty society or hard environment. Pine and cypress: Gentleman. Therefore, it can be understood that only in a difficult environment and a dirty society can we know who a real gentleman is.
