@Test
    public void test() {
        String province = "河北省";
        String city = "石家庄市";
        String district = "桥西区";
        //简码 --->> HBSJZQX
        province = province.substring(0, province.length()-1);
        city = city.substring(0, city.length()-1);
        district = district.substring(0, district.length()-1);

        String info = province + city + district;
        String[] headString = PinYin4jUtils.getHeadByString(info);
        String shortCode = StringUtils.join(headString);
        System.out.println(shortCode);

        //城市编码 --->> shijiahzuang
        String cityCode = PinYin4jUtils.hanziToPinyin(city,"");
        System.out.println(cityCode);
    }
