Ceng Shiqiang said I ching 10 Kun gua.

1. Among the twenty-four hexagrams in the Book of Changes, there is only one pure yang hexagram representing heaven and one pure yin hexagram representing earth. These two hexagrams are completely opposite and can never be separated. Gan Kun is a husband and wife at home and a monarch and minister in society.

2. As for the Book of Changes, it is called "people use it for daily use without knowing it". In fact, we use it every day, but we just don't know we are using it. Kungua means "cooperation, sincere support, happiness and perfection". Kun hexagrams use six, emphasizing "loyalty and righteousness" that is, unchanged, doing hexagrams is creation, and Kun hexagrams is cooperation. Since ancient times, the best person to carry forward Kundao is Zheng He of the Ming Dynasty. He played well in every game and won glory with his humble position. All his life, he benefited from the phrase "justice is liberated from people's hearts."

3. Kungua's first thought: "When you step on the frost, you should think that it is very cold this winter, and you should be prepared in advance. This is God's warning to you, that is, you should be aware of subtle changes and be highly vigilant; Second, "there is no harm in learning": straight is upward, square is position, and big is magnanimity. There is no harm in not learning to abuse, that is, you can't be complacent and get carried away after making some achievements; The third is "containing Zhang Kejian, or doing things from the king, achieving nothing": containing introverted, rational in mind, decent in mouth, or confused, doing things modestly and cautiously, and doing things wholeheartedly; Fourth, "no complaints and no reputation": what to say is very important, listen more and talk less; Fifth, Yuanji: Yellow stands for coordination, and this level must be maintained.

4, one person can't please, please everyone, you can't please anyone; Don't refuse when it's the leading role, but feel at ease when it's the supporting role.

5. The six hexagrams in the Book of Changes represent six stages of life. Everyone has been climbing on these six hexagrams all his life, and he has climbed higher and higher from them. The best state is to climb to the fifth, and generally it will be miserable at the sixth. Enough is enough, don't be too demanding, this is always the truth of nature.
