阅读下列材料，回答有关问题。

材料一  新交因狐裘而订，不问出身。旧友以鹑结（指破烂的旧衣服）而疏，视同陌路。遂令舆台隶卒辉煌而上友，官绅寒士贫儒褴褛而自惭形秽。——摘自《申报》：1873年4月7日《申江陋习》

材料二 道光季年，中外通商而后，凡西人之以货物运至中国者，陆离光怪，几于莫可名言。华人争先购归，以供日用。初祗行于通商各口岸，久之而各省内地亦皆争相爱慕，无不以改用洋货为奢豪。一摘自《申报》：1892年1月18日《中国宜造洋货议》

材料三 风俗之靡不自今日始矣，服色之奢亦不自今日始矣。溯当立约互市之初，滨海大埠，富商巨贾与西商懋迁有无，动致奇赢。财力既裕，遂于起居服食诸事斗异矜奇，视黄金如粪土，见者以为观美，群起效之。……近今风俗之侈靡日甚一日，较之三十年前已有霄壤之别。——摘自《申报》：1894年3月16日《论服色宜正》

After achieving a 9 percent GDP growth, hosting a successful Olympic Games and carrying out its first space walk, you'd think China would be happy．Yet China is not pleased．That at least is the opinion of a new book written by a group of Chinese authors．

China Is Not Happy was released in March．It is a follow-up to the 1996 work China Can Say No, a bestseller that complained about the influence of the West, and the US in particular, on China．Thirteen years later, the authors of China Is Not Happy list their dissatisfaction with how China is being treated in the world today．They argue that China needs to use its growing power and economic resources to build its own position of outstanding performances．"From looking at the history of human civilization, we are most qualified to lead this world．Westerners should be second," the book says．

The authors, single out the US for special scorn (轻蔑), and say their book's message has been helped by the economic crisis．"This economic problem has shown the Chinese people that America does have problems, and that what we've been saying is right," said Wang Xiaodong, one of the authors in an interview with The Wall Street Journal．Since being released on March 13, the book has become a bestseller in many Chinese bookstores．The publisher has printed 270,000 copies, and says sales are far better than expected．

Yet much of the response to the book has been negative．Several reviews in the Chinese media have criticized the book's radical opinions．The book is a way to "fish money from the pockets of the angry youth and angry elderly," wrote one critic in the China Youth Daily．Meanwhile, a well-known sociologist, Li Yinhe, has said that China needs patriotism (爱国精神), but there is a limit．In her blog she wrote, "If we are to bully other countries, take the world's resources and try to lead it, we're going over the top." Wang Xiaodong admitted in an interview with the US' Time magazine that the book's title is a bit of a trick．"Those words in the title are just for the purpose of promoting the book in the marketplace," he says．"We didn't choose them．It was the people selling the book who chose the title, because it would sell well."
