   It is well known that a luminous early type galaxy has hot halo
   surrounding the galaxy. To explain a total amount of hot gas and energy
   source, many evolutionaly sequence for the gas flows are proposed.
   According to the sequence by Ciotti et al. 1991, elliptical galaxy
   would pass through initial wind phase. In order to examine the
   existence of wind phase, we will propose to observe the prototypical
   merger remnant NGC 7252, the Atoms-for Peace galaxy. This galaxy is
   considered to move to an eraly type galaxy. This observation have an
   impact for chemical evolution of intracluster medium.
