The light-cone distribution amplitude (LCDA) encapsulates the nonperturbative information of the hadronic states in hard exclusive reactions. The envisioned Circular Electron Positron Collider (CEPC) has the potential to access the pion LCDA at an unprecedented level of accuracy with its clean background, broad energy range, high luminosity and precision measurements. Such knowledge can not only deepen our understanding of the composite hadron structure, but also provide new insights for exploring the intricate structures of the underlying non-abelian gauge theory (QCD).
