Why is Laozi's Tao Te Ching the best one to explain the Book of Changes?

Never heard of it. I have been studying prophecy for nearly a year, focusing on the Book of Changes, including the Book of Changes, the notes and comments of sages, and the works of some ancient fortune tellers such as the Meihua Yijing. , and modern vernacular explanations, but no one has ever used the Tao Te Ching. Because the Tao Te Ching is inoperable, in other words, it is useless.

Tao Te Ching says that the mysterious is both mysterious, as if everything can be included, but what is included? Although they are based on the same philosophical concepts, there is no intersection between them. Explaining the Book of Changes with Tao Te Ching is as ridiculous as explaining Xunzi with Han Feizi.
