Can't figure out inflation

Wen _ Ching Chuluwi RMB exchange rate has risen steadily over the past few years, and in a twinkling of an eye, the Hong Kong dollar has been much cheaper than the renminbi.　　Before going to Shenzhen, taxi drivers like to collect HKD, of course, now different. For those who have a Hong Kong dollar income, it is not very impressive to stay in the territory, or to spend money in dollars, but if you go to the mainland or some other country, you will feel that your income has been reduced in disguise.　　Previous retirement in the mainland was the choice of many elderly people in Hong Kong, but the recent increase in the number of elderly people returning to Hong Kong was due to the rapid growth of medical and living expenses in the mainland. Many mainland media have carefully compared the prices of the same brands, and found that the mainland is now much more expensive. Another point, that is, if not the original import but the joint venture company's brand products, the quality is very different.　　If the original import, because to add tariffs, the price can be understood, but these local production of locally produced products sold expensive, if the ratio between the two places in the proportion of per capita income, it is obvious that the mainland residents are much more expensive. This is a problem I can't think of.　　Found some articles, such as the autumn Wind, "how can the inflation cordon rise, how can The Economist nonsense", that the issue of money to lead to inflation, is the government's behavior, but this Hong Kong people said the waterproof way, the United States more waterproof, why do not see Americans affected by inflation? It is also recommended that the Chinese people's University School of Economics associate professor of "Why" made in China cheaper in the United States? 》。 The author said four reasons, brand effects, transaction costs, intellectual property rights, as well as consumer culture, but still do not understand, is really the problem in consumers, money, people stupid?
