It's one of the most important venues during the Olympics. Now it has been changed into a comprehensive recreation water park. The most impressive part is the Donation Wall, very few people know that more than 90% of the fund for building the Water Cube was donated by overseas Chinese Leaders, when I received them as honorary guests for the celebration of 60 years anniversary of founding of new China, they visited the Water Cube and proud to find their names on the glass name wall.Chinese always have their Roots in China no matter where they are. It was a very touching moment that I will never forget.
