4. prepare font song.ttc, and generate font files
   

   fontforge -script subfonts.pe simsun.ttc song Unicode.sfd
   

5. create bash script makemap.sh, run the script to generate map file
   

   if [ -f song.map ]; then
       rm song.map
   fi
   for i in *.tfm
   do
       echo "${i%.tfm} ${i%.tfm} <${i%.tfm}.pfb" >> song.map
   done
   

6. create c70song.fd

    mkdir -p ~/texmf/fonts/type1/CJK/song

    cp *.tfm      ~/texmf/fonts/tfm/CJK/song
    cp *.pfb      ~/texmf/fonts/type1/CJK/song
    cp c70song.fd ~/texmf/tex/latex/CJK/UTF8
