Connected in series under the basic tree structure, the buildings form a dynamic relationship. The central corridor with broken lines stretches like the tree trunk, and the four teaching buildings are arranged on both sides like the tree branches, forming the main teaching area. Dense grilles are used for the southward external façade of the building, forming semi-transparent partition. The sunshade over the corridor, as the major public area, unfurls like cloud, and such poetic elements are also used in porches, corners and other places.
