Introduction to Sheepskin Raft: Sheepskin Raft, commonly known as "Paizi", is an ancient ferry tool. The head and hooves of a goat are cut off, and then the sheepskin is stripped off, the mouth is pierced, and the mouth is blown while using it. Make it bulge, and a dozen "paizi" made of "huntuo" can be carried by one person, which is very light. Tourists sit on the "paizi" and the rafters paddle the raft forward, which is very interesting.
