Was Hillbilly invented by Shanghainese?

No, hillbilly was not invented by Shanghainese. In our early films, such as "Grain", "Guerrilla in the Plain" and "A River Flows East", we will find lines calling farmers hillbillies. Some landlords, warlords, bullies and traitors have this bad habit of looking down on rural people. In the past, Shanghainese used to call foreigners country people. With the progress of the times and the narrowing of the gap between urban and rural areas, there are fewer and fewer voices that despise foreigners.
