Baijiu, also known as Chinese liquor, is a traditional Chinese spirit made from fermented sorghum or other grains. An exhibition hall effect drawing typically refers to a visual representation or illustration of a planned exhibition hall, showcasing the design and layout of the space. This could include the display of Baijiu bottles, shelves, and decorative elements, all rendered in a realistic or artistic style. It is a tool used in architecture and design to present the vision of a space before it is constructed.
