Can Vietnamese understand the Zhuang language of Chongzuo?

It's so interesting, Yanzhong Zhongdu, a handsome guy who is keen on learning Chinese! Where is your grandmother's house in Longzhou? I am from Longzhou, too. People there generally call the local Zhuang language a dialect. Now I can only understand half of Longzhou dialect. When I was a child, I was quite good at speaking, but I forgot a lot when I went out for many years and didn't have a chance to practice oral English (my family speaks vernacular). I think there is no problem in the communication between Chongzuo dialect and Longzhou dialect, but the accent difference is quite obvious. Guangxi Zhuang language is divided into two major language families, with Longzhou as the main language family in the south, including Pingxiang, Chongzuo, Ningming, Daxin, Tiandeng, Fusui, (Shangsi, Jingxi and Debao); The northern part is dominated by Wuming, which covers a wide range, including several subordinate counties in Nanning, Baise and Hechi. These two representative places have Zhuang language schools respectively, but it seems that the current Zhuang language textbooks are all based on Wuming, right?
