Taipei Mayor Hau Lung-bian said Sunday that with the steady increase in the number of visitors to the 2010 Taipei Flora Expo, he is no longer worried about too few visitors, but rather about too many visitors. Hau said that at present, visitor numbers at the expo are increasing rapidly. The mayor said that contrary to allegations, he is not concerned about too few visitors. 'In fact, I am more worried that too many visitors each day could compromise the quality of the experience,' he said. Hau was responding to reports by the Liberty Times newspaper citing parents who said their children's school have arranged for students to have two outdoor education sessions at the expo twice each semester and who questioned whether the expo wants to 'make use of school students to help boost the number of visitors.' Asked if he is satisfied with the results of a survey showing that office workers who have visited the expo gave an average of 73.2 out of a perfect 100 points on the expo, Hau said that he accepts the views of the public. But he also said he is gratified that most of the people are satisfied with the expo. The expo kicked off its six-month run Nov. 6 with an opening ceremony in which Doeke Faber, president of the International Association of Horticultural Growers (AIPH) , praised it as the best he has seen in 50 years. As of noon Sunday, the number of visitors to the expo had broken 1.4 million.
