Abstract：In the undergraduate graduation design of Tongji University in 2019, the working group again selected Lujiazui as the
object, and carried out teaching experiments for the re-urbanization of the contemporary Chinese new city. The experi-
ment revolved around the possibility of transformation and remodeling of Century Avenue, and attempted to redefne the
space of 5 km in length. Through the sinking of Century Avenue, the space stitching of the entire small Lujiazui area was
completed in order to supplement the composite function and improve the space quality. Thus, the Century Avenue could
be transformed into a memory-saving and humanistic urban axis with enhanced vitality.
