The most beautiful moment of the Olympic opening ceremony

While watching the Olympic opening ceremony, I wanted to write something down. However, my limited vocabulary cannot describe this feast for the eyes. I wrote four words in the QQ group with my buddies: "tan wei guan zhi" (speechless). Actually, I'm not sure if I used the right words. When I said it, I was even wondering what "tan wei guan zhi" really means. I believe that most of the friends are watching this grand performance at this moment. Art, culture, science and technology, and humanism are cleverly blended. This is the highest point of integration between science and technology and art in a country.
