  This is an introductory article on high dimensional knots for the beginners.
High dimensional knot theory is an exciting field. It is a field of knot
theory, which is one of topology and is connected with many ones. In this
article we use few literal expressions, equations, functions, etc. We barely
suppose that the readers have studied manifolds, homology theory, or topics
beyond them.
  Is there a nontrivial high dimensional knot? We first answer this question.
After that, we explain local moves on high dimensional knots and the
projections of high dimensional knots.
