Finding a Hamilton graph from simple connected graphs is an important problem in discrete mathematics and computer science. Grinberg Theorem is a well-known necessary condition for planar Hamilton graphs. It divides a plane into two parts: inside and outside faces. The sum of inside faces in a Hamilton graph is a Hamilton cycle. In this paper, using a basis of the cycle space to represent a graph and by the Inclusion-Exclusion Principle, we derive the equality with respect to the inside faces that can be also obtained from Grinberg Theorem. By further investigating the cycle structure of inside faces, we give a new combinatorial interpretation to Grinberg's condition, which explains why Grinberg Theorem is not sufficient for Hamilton graphs. Our results will improve deriving an efficient condition for Hamilton graphs.
