What did the authentic people in Rong County, Guangxi say?

Rongxian people call what they say "Rongxian vernacular". Rongxian County is located in the Pearl River Valley, and "Rongxian Vernacular" is a branch of Cantonese. There are many words in Rongxian vernacular, which are classical Chinese words in China's ancient works and books. In modern books, newspapers and magazines, these words are no longer in circulation, so the locals can basically only speak but not write. These words are called "Chinese elegant words" by academic circles and are "living fossils" of ancient Chinese.
