The public can enjoy exciting performances by California state champions Nic and Tristan Puehse at the lawn in front of the building, the tallest in China's mainland, at Lujiazui free of charge.

The talented twins, who are nine years old, took the first and second places in their very first competition in California, the United States in 2004 when they were only seven years old. Two months later, they skateboarded to gold and silver at the California State Games.

"Nic and Tristan don't have a coach; they do however, watch videos and local skateboarding veterans to enhance their skills," said Michael Puehse, the father of the twins.

Unlike other school kids, Tristan and Nic do not go to school but study at home taught by their mother.

"They practice skateboarding for three hours every day, five days a week; and they spend the same amount of time on study," said the father.

Local and national sponsors have been more than willing to have Nic and Tristan promote their products such as skateboards, sunglasses and sports wear.

The public can catch the two boys perform three times a day at 10am, 1pm and 3pm until May 6.

Jack Lee, marketing manager of Realone-Sports Market Communication & Consultancy Company, said his firm planned more skateboarding activities in the future including a theme camp at a skateboarding park in New Jiangwan Town, Yangpu District, in the summer.
