This is the main way Chinese emacser used, like below, but it 
will have question 2:  Chinese Char Height > Ascii Char Height.

   'default nil
   :font (font-spec :name "PragmataPro"
                    :weight 'normal
                    :slant 'normal
                    :size 16.0))
  (dolist (charset '(kana han symbol cjk-misc bopomofo))
     (font-spec :name "黑体"
                :weight 'normal
                :slant 'normal
                :size 16.0))))
