What is the difference between "nothing" in Buddhism and "nothing" in the Yi Jing?

The meaning of Wu in Buddhism in the "Diamond Sutra" means non-attachment and no forgetfulness. As the saying goes, "All appearances are empty and forgotten, like bubbles in dreams, dew, or lightning. Observe like this. "

Nothing is not the absence of existence, but..., for example, if you look at a mirror, does it leave any image after it is reflected in the mirror? Of course not. , when the object image is gone, the mirror will return to its previous state of nothingness, without any trace of it. This state is what humans call non-attachment, that is, nothingness.
