What are the similarities and differences between eight characters and crape myrtle?

There is a book called The History of China's Numerology, written by Lu Zhiji, which talks about the connection and difference between the two. The eight-character theory is relatively perfect, many people practice it, and the system is relatively complete. Wei Zi pays more attention to experience, but his theoretical level is not enough. To put it simply, the eight characters are already academic, while Wei Zi is just an experiential skill. Many experts and scholars think so, and I agree with them, so I put it forward for your reference. Of course, you can have more opinions and learn more.
