The Shanghai Oriental Art Center (Chinese: 上海东方艺术中心, p Shànghǎi Dōngfāng Yìshù Zhōngxīn), abbreviated SHOAC, is one of the leading performance and cultural facilities in Shanghai, China. The five interconnected hemispherical halls or "petals" are shaped to resemble a butterfly orchid from above. They comprise the Entrance Hall, the Concert Hall, the Opera Hall, the Performance Hall, and the Exhibition Hall. The high-tech ceiling changes color during the night to reflect the nature of the performances inside.
