   Our knowledge of the Galactic X ray sources is quite incomplete due
   to the Galactic absorption (low energy band) and limited spacial
   resolution. Due to the limited information, we are till unable to
   answer the origin of the Galactic diffuse hot plasma, and total
   number of supernova remnants, X ray pulsars, and other low luminosity
   X ray sources. We propose a galactic plane survey of the inner
   galactic ridge. ASCA provides us with the first opportunity to reveil
   the galactic absorption and make unbiased sample of many category of
   the galactic X ray soruces.
