The survey said the Olympics not only built up China's image but also served as an advertisement for China's tourism. The online survey was conducted on consumers in 16 countries and regions before Games' opening ceremony and after the closing. About 80 percent of the respondents had not been to China before the events and 50 percent of them expressed hopes of visiting China after the Games. According to the survey, 70 percent of the respondents felt Beijing was more modern and scientific than what they had thought. The most interested respondents were from Singapore, India, Mexico, South Africa and the Republic of Korea, as well as China's Hong Kong and Taiwan.
