Hangzhou Grand Theatre was built in 2004. It is the first landmark building in the Qianjiang Age in Hangzhou, designed by Carlos Ott, a famous architect. Hangzhou Grand Theatre's logo modelling is to concentrate its special angle in the graphics. In the design of lines, it not only expresses the international vision, but also retains the nature of traditional brushwork. The curvature of the Grand Theatre is divided into sections in the middle section, which is similar to the A letter distortion of Art, and expresses the main idea of the Grand Theatre.
