Do all people in Guzhu Town, Zijin County, Heyuan City, Guangdong Province speak Hakka?

People in Zijin County basically speak Hakka

There should be another Guzhu dialect in Guzhu Town, which is similar to Heyuan dialect, Linjiang dialect in Linjiang town, and Huang She (pronounced twice) in Tangzhen has a similar sound, so it should be considered the same dialect but different accents. People in these places speak two languages. Generally speaking, they respond to whatever the other party says.

So there are actually two dialects in Zijin County.

I am from Huangtang Town, Zijin County, and I can speak two languages.
