The sculpture of "Split Ball" is located on the lawn in front of the gymnasium in the East Campus, was created and completed by teacher Li Xianfeng from my art college in 2003. The dissected sphere forms a continuously expanding colored staircase visually, just like the sphere releasing a continuous stream of energy; Lines of different colors stretch out layer by layer from a silver sphere, with brilliant colors and unique shapes, attracting the attention of countless visitors. The layers of stairs symbolize the continuous climbing and growth of students on campus with the help of knowledge, and also symbolize that our campus is a harmonious and orderly whole; The layers of changing colors represent the richness and diversity, youth and vitality of university campus life. The spherical printing with reflective material highlights the bright green lawn, trees, and the crowds coming and going, reflecting its design concept of combining humanities and nature, which is also in line with the educational philosophy of China Agricultural University to adapt to nature and green development.
