Moir\'e superlattices of tunable wavelengths and the further developed moir\'e of moir\'e systems, by artificially assembling two-dimensional (2D) van der Waals (vdW) materials as designed, have brought up a versatile toolbox to explore fascinating condensed mater physics and their stimulating physicochemical functionalities. In this Perspective, we briefly review the recent progress in the emerging field of moir\'e synergy, highlighting the synergetic effects arising in distinct dual moir\'e heterostructures of graphene and transition metal dichalcogenides (TMDCs). A spectrum of moir\'e of moir\'e configurations, the advanced characterization and the exploitation efforts on the moir\'e-moir\'e interactions will be discussed. Finally, we look out for urgent challenges to be conquered in the community and some potential research directions in the near future.
