The Old Biology Hall of Tsinghua University stands as a representative campus building designed by Yang Tingbao in modern times. Externally, its restrained neoclassical red brick facade creates a solemn academic aura, while internally, the spaces are tailor-made centering on the core functions of biological experiments, specimen preservation and plant cultivation. In terms of campus planning, it establishes a well-organized modern science complex. After heritage conservation renovations, it successfully integrates the historic structure with modern life science teaching. It is a dual classic of modern Chinese science and education architecture as well as historic building adaptive reuse.Model making software: 3ds Max 2014 Rendering software: vray3.60.03 for 3ds Max 2014
