(Ni Xing Fu Ma?)" by a CCTV reporter, he looked confused before replying, "My family name is Zeng. (Wo Xing Zeng.)" This has become a joke. But his answer showed migrant workers and TV reporters live in different worlds and they cannot even communicate with each other. Similarly, when asked, "Are you happy?" a 73-year-old man, collecting used plastic bottles in a street in Zhejiang, said, "The bottles can be sold for 0.1 yuan each." Asked again, he said, "The government is good." The reporter went on, "My question is 'Are you happy?'" The old man answered, "My hearing is not good."
