One of the world s largest human resources service agencies, Mercer, recently released the Global Cost of Living Survey 2012, which states that Tokyo is the world s highest cost of living; Hong Kong, China ranks 9th; Shanghai, China And Beijing ranked 16th and 17th respectively; New York has the highest cost of living in the United States, but ranks 33rd in the world. The "cost of living" announced by Mercer specifically refers to government agencies and multinational companies stationed overseas in various cities The cost of living is not the same as the cost of living of residents in general. It confuses two different "costs of living", which is not only helpful for scientific comparison, but also easily leads to emotional tendencies. What does this text mean? ['The cost of living in Shanghai and Beijing is not higher than in New York.', 'Confusion over the concept of "cost of living".', 'Costs of living in cities in different countries are not comparable.', 'The cost of living for residents of large cities in China is not high.']
