Prominent Taiwanese dancer Sheu Fang-yi, Taiwanese pop sensation Lin Yu-chun and the world renowned Cloud Gate Dance Theatre will help usher in the Taipei International Floral Exposition in a celebration Saturday night after the event's grand opening in the morning. Organizers said Taiwanese soprano Chen Mei-ling, the Taipei Symphony Orchestra, and the Taipei Philharmonic Youth and Children's Choir will also be part of the performance that starts at 8: 30 p.m. at the Pavilion of New Fashion in the expo's Yuanshan Park Area. The evening celebration will be brought to a stirring conclusion by 50-minute long fireworks display at the Dajia Riverside Park and Dadaocheng District starting at 9:10 p.m. The show will kick off with a magnificent display in which the Chinese characters of the expo's official name will light up Taipei's sky. That will be followed by a 30-minute fireworks show showcasing five teams from Taiwan, the United Kingdom, Italy, Spain and Sweden. Besides the traditional confetti-style fireworks, the show will also feature over 2,000 'red lantern' and 'red dragon' rockets lasting 40 seconds. At 9: 30 p.m., another string of fireworks will be set off from the Keelung River to the Danshui River, with the highlight a fireworks display of the expo's official logo. Fireworks displays of the country's national flower -- the plum flower -- a five-colored heart-shaped display symbolizing the friendship shared by the five continents of the world, and an outline of Taiwan are also expected to be among the show's top hits. Although possible rain is in the forecast, organizers said precautions have been taken. Unless the rain became too heavy, the show would take place as scheduled, they pledged. During the day, people dressed in Japanese kimonos and traditional Thai costumes will be at the expo venues to draw visitors to their country's exhibits. In the afternoon, pop singer Della Ding and the highly popular Champion Band will provide live entertainment at the Dajia Riverside Park Area. Democratic Progressive Party (DPP) Taipei mayoral candidate Su Tseng-chang said he would also visit the expo Saturday. Starting tomorrow, free Wi-Fly services will be available over the entire 91.8 hectare expo site to allow for wireless Internet connections.
