Nevertheless, the place of local Cantonese language and culture remains contentious. A 2010 proposal to switch some programming on Guangzhou television from Cantonese to Mandarin was abandoned following massive public protests, the largest since the Tiananmen Square protests of 1989. As a major economic center of China, there have been recent concerns that the use of Cantonese in Guangzhou is diminishing in favour of Mandarin, both through the continual influx of Mandarin-speaking migrants from impoverished areas and strict government policies. As a result, Cantonese is being given a more important status by the natives than ever before as a common identity of the local people.
