-> The example displays the older `zh-CHS` and `zh-CHT` culture names with the 0x0004 and 0x7C04 culture identifiers, respectively. However, your Windows Vista applications should use the `zh-Hans` name instead of zh-CHS and the `zh-Hant` name instead of zh-CHT. The `zh-Hans` and `zh-Hant` names represent the current standard, and should be used unless you have a reason for using the older names.
