Twelve-year change of geomantic omen

The source of the sentence "The wind and water turn, come to my home next year": According to the ancient Chinese calendar, one flower in 60 years is called one yuan, and three flowers in 180 years are called three yuan. Every 20 years is luck, a total of nine times. Ancient astrologers believe that every 20 years, there will be different stars that affect people in turn. So there is no eternal land of feng shui.

Moral: Good luck will not always belong to you, good luck will not always follow you, and good things will not always accompany you. Your life can't be smooth sailing forever, and you can't drink cold water all the time. This is the same as thirty years in Hedong and thirty years in Hexi, which shows that a person's life is ups and downs and cannot be dull forever. To put it bluntly: now you are lucky and I am unlucky, but you will not be lucky forever, and I will not be unlucky forever. There will always be an upside down day. It's my turn to be lucky, but you're unlucky.
