Highly intricate surface architectures derived from patterned polymer microstructures have received increasing concern in recent
years. Directional photo-manipulation (DPM) of azopolymers is one of the effective strategies to tune the patterned polymer microstructures
through directional mass migration (DMM) upon polarized light illumination. In this feature article, we emphasize the latest advances of
DPM on azopatterns created by self-assembly. The mechanism of DMM, the photo-manipulation performance, and functions of
manipulated patterns are introduced in sequence. As presented, DPM can manipulate the as-prepared microstructures feasibly by taking the
advantages of non-contacting and nondestructive characters. Moreover, the challenges and opportunities of DPM strategy are discussed in
