    public static boolean hasChinese(CharSequence content) {
        if (null == content) {
            return false;
        }
        String regex = "[u2E80-u2EFFu2F00-u2FDFu31C0-u31EFu3400-u4DBFu4E00-u9FFFuF900-uFAFFuD840uDC00-uD869uDEDFuD869uDF00-uD86DuDF3FuD86DuDF40-uD86EuDC1FuD86EuDC20-uD873uDEAFuD87EuDC00-uD87EuDE1F]+";
        Pattern pattern = Pattern.compile(regex);
        return pattern.matcher(content).find();
    }
