调用方法：
     public string ConvertToChineseNumber(string old)
            {
                Chinese ch = new Chinese();
                long num = Convert.ToInt64(old);
                string re = ch.returnResult(num);
                if (re.StartsWith("壹拾"))
                {
                    re = re.Substring(1, re.Length - 1);
                }
    
                return (re);
            }
