The Second Teaching Building, also known as the "West Building", was built in December 1953 and is one of the earliest buildings in the East Campus, It was also completed at the same time, including the Democracy Building, cafeteria, water tower, machinery warehouse, internship factory, and school gate, etc. Among these earliest buildings, some have been demolished, and the West Tower is one of the preserved old buildings. The building area of the West Building is 6000 square meters, including 2 classrooms with 200 people, 6 classrooms with 120 people, and 36 classrooms with 50 people; At the beginning of its construction, it served as an office, teaching and research office, and library. The first batch of agricultural mechanization talents trained in New China all spent unforgettable university time here. After more than half a century of vicissitudes, the West Building is now renamed as the Second Teaching Building and remains one of the main teaching venues of the school. Designer and technical expert Wang Chaojie planned and constructed this building with the policy of "economy, applicability, and sturdiness". The building is similar to contemporary and later buildings, reflecting a simple and minimalist architectural style. Only convex bricks are used as decorations on the exterior walls, giving the exterior facade of building a special texture and beauty, and form a sense of rhythm and rhythm with ups and downs.
