Is Duke Zhou still practical today?

Very useful, but not easy to detect. It seems that we are short of money these days. I dreamed of snakes and big fish the night before yesterday. The next day, my parents gave Cary 2000 yuan. Because I was deeply impressed, I went to Baidu to learn the meaning of this dream. As a result, I dreamed that snakes and fish were lucky, and unexpected good things would happen.
