Explain the social meanings While majoring International Business in Guangdong University of Foreign Studies, a student of IB 2012 once wrote his own image on China and what he actually saw in modern Chinese cities: "The image I had of China was its large number of people striving for survival and the Great Wall. I did not expect to see huge cities like Beijing, Shanghai and Guangzhou. China was incomparable to countries like the United States or the UK. I was actually wrong. In the three big cities we are able to enjoy an international standard of living at much more affordable rate." Explain his observation from the perspective of China's social transformation.
