 public static Boolean Iscarnumberno (String carnumber) {/
     *
     license plate number format: Kanji + A-z + bit-A-Z or-
     (includes only the common license plate number, Coach car and some of the military vehicle grades are not included)/
     String carnumregex = "[\ue-\ufa]{}[a-z]{}[a-z_-]{}";
     if (Textutils.isempty (Carnumber)) return false;
     else return carnumber.matches (Carnumregex);
   }

Of course, this regular expression has limitations, such as the first limit is only Chinese characters, not limited to only 34 provinces of Chinese characters abbreviation; the license plate number does not exist the letters I and O, prevents and 1, 0 confuse, some license plate cannot distinguish and so on.
