   The Galactic Center is full of unresolved hot plasma and the diffuse
   neutral iron K-line, of which the origins are still an enigma. One of
   the keys for those problems is, the shape for the former, and the
   correlation with the molecular cloud distribution for the latter.
   However, we could not enough quantitatively constrain them with
   previous ASCA data, mainly due to lack of the observation area with
   good statistics. We accordingly propose the Galactic Center intensive
   survey with ASCA. ASCA has large field of view, and is suitable for
   this survey. This survey would provide good quality data to reveal
   their structures. We will also find many new sources, some of which may
   have peculiar nature, and can study the supernova remnants and other
   diffuse structures in this region in detail.
