The Bihai Silk Road Grand Theatre is located on the Tiantian Performing Arts Island in Beihai Garden Expo Park. The exterior design concept is derived from the marine organism – sea urchin. The building shape resembles a sea urchin. Its function mainly meets the needs of large-scale performances and large-scale conferences. On the exterior structure of the theatre, 1120 LED lights are installed. The colors are rich and vivid with high brightness. In terms of form, it can combine dynamic and static, and alternate between fast and slow. It echoes the scene of other buildings in the park being brightly lit at night, lighting up and beautifying the never-sleeping harbor. It is like a golden crown shining brightly at night.
