The Silence Tide, is a unique natural phenomenon unique to Buji Island.
At the turn of spring and winter each year, around the time of the Forbidden Magic Festival, when the Return Soul Poplar sprouts its first bud, a school of Wenchuan Fish from the deep sea return home, trekking up the wide and deep Silent River with their plump and strong bodies.
An ancient book says: The Wenchuan fish, resembles a carp, with the body of a fish and wings of a bird. They are blue in colour, with white heads and red beaks, usually swimming in the western sea, returning to the eastern sea, and settling in Buji, flying at night. Their sounds resemble phoenixes and roosters, their taste is sour and sweet, they drive one insane when consumed, and their appearance signify great prosperity.
