As a comfort to people waiting outside in hot weather, the Republic of Korea Pavilion is distributing 1,440 bottles of mineral water to visitors every afternoon. Nearly 100,000 bottles have been handed out since May 26.

Meanwhile, the Expo Organizer has increased sun shelters and spray cooling systems along the venues and even placed large ice cubes near long waiting lines to keep people cool.

Yesterday was the city's hottest day so far this year with temperature reaching 39.6 degrees Celsius.
