     With the PV-phase observation, we found that the soft X-ray emission
    (1.5-3.5 keV ) seems to be diffuse with a peak at the position of the
    Galactic center SgrA*, while in the hard X-ray band ( 3.5 - 10 keV ),
    we discoverd a heavily  obscured source only about 1' away for the   
    Galactic center. The diffuse iron  line energy is around 6.7 keV. How
    ever an additional line at the energy of 6.4  keV is found along the 
    north Galactic plane from the Galactic Center.  We propose a follow- 
    up observation to study possible relation of the point  source ( hard
    source ) and the diffuse 6.4 keV line structure.
