Do Ni Xiahai and Ceng Shiqiang know each other?

Connie Xia Hai and Ceng Shiqiang don't know each other. The only connection is that both Ni and I use the Book of Changes.

1. Among them, Ceng Shiqiang mainly talks about management with the knowledge of the Book of Changes. Classic works are the Book of Changes, and it is really easy to wait for a series.

2. Ni mainly combines the knowledge of geography in the Book of Changes, and his classic works include Tianji and Renji.
