Linguistic conflicts related to Cantonese include incidents like the Guangzhou Television Cantonese controversy, and one where a school in Guangzhou which introduced a Cantonese-only textbook into classes was accused of "promoting separatism" by some northerners.[14] The project was shut down by local authorities because of the controversy [14]. The suppression of the Cantonese language as well as the mass migration of non-Cantonese speaking people in to the area, (only about half of Guangzhou's population are Cantonese natives, in recent times) have caused some Cantonese enthusiasts to accuse the local authorities of wanting to commit "cultural genocide" of the Cantonese language.
