I don't know if someone else has ever met Program Drop-down lists of frequently used regions. Great land in China! There are so many provinces, regions, counties and cities! If every list box is written to the program, it is too troublesome. Therefore, consider loading the data with an XML file.
The XML file format is as follows: <? XML version = " 1.0 " Encoding = " UTF-8 " ?>
