  We study the role of transition rule in high-order harmonic generation from
solids driven by linearly polarized laser elds. The orientation-dependent
transition dipoles can regulate the emergence of the multi-plateau structure.
In the multi-plateau zone, however, di erent from the mechanisms of
step-by-step excitation reported previously, we nd that the emission time and
orientationdependent yields exhibit synchronization and more ne patterns,
respectively. And the orientationdependent yields and its ne patterns can be
attributed to the collective contribution of the transition rule and
quantum-path interference. Therefore, to better understand the constructive and
destructive patterns in the orientation-dependent yields, we propose a scheme
of intercycle interference, which can further be utilized as a tool to image
the structure of the solids and provide an avenue to optimize the electron
dynamics in solids for the production of attosecond pulses in a compact setup.
