regioncode              'regioncode' is developed to conquer the
                        difficulties to convert various region names
                        and administration division codes of Chinese
                        regions. In the current version, 'regioncode'
                        enables seamlessly converting Chinese regions'
                        formal names, common-used names, and geocodes
                        between each other at the prefectural level
                        from 1986 to 2019.
