Does the wolf fang have any meaning in Feng Shui?

There is no explanation,

Wolf fangs are Mongolian ornaments, because Mongolians believe that they are descendants of gray wolves and white deer, and wolves are creatures with supernatural powers.

In the traditional culture of the Han people, the wolf itself is evil. It’s just that wolf culture has emerged in the Han region in recent years, and some Han people have imitated the Mongolians in wearing wolf fangs.

There has never been any record of wolf fangs in Feng Shui.
