The organizer of the 2010 World Expo yesterday recommended Expo ticket holders should replan their visits to avoid overcrowding near the end of the fair.
The suggestion was made due to a fall in visitors yesterday to 85,564, the least since the Expo officially opened on May 1.
The World Expo's fourth day, the first for which standard day tickets applied, attracted more than 140,000 visitors, beating the previous day's 131,700 but fewer than anticipated.
An Expo Bureau press official said yesterday that if large numbers of visitors intend to visit the site later, overcrowding can't be avoided, therefore, the organizer urges people to reschedule.
By May 4, over 33.11 million tickets had been sold. With free tickets given by the Shanghai government to every household, the potential number of visitors is more than 40 million.
