A place name reflects the continuum of life history in a location and therefore must itself have a long life. However, a large number of places have been given names that only existed for a limited time. In fact, there are place names that confuse rather than facilitate distinction. Therefore, to make it more reasonable, it is advisable to adjust the places that no longer hold the right function to distinguish one place from another. In this adjustment work, consideration should also be given to names of persons whose mention in a place may evoke negative connotations.
