  The main purpose of the present paper is to discuss whether or not the
collective flows in heavy-ion collision at Fermi energy can be taken as a tool
to investigate the cluster configuration in light nuclei. In practice, within
an Extended Quantum Molecular Dynamics model, four $\alpha$-clustering (linear
chain, kite, square, and tetrahedron) configurations of $^{16}$O are employed
in the initialization, $^{16}$O+$^{16}$O around Fermi energy (40 - 60
MeV$/$nucleon) with impact parameter 1 - 3 fm are simulated, the directed and
elliptic flows are analyzed. It is found that collective flows are influenced
by the different $\alpha$-clustering configurations, and the directed flow of
free protons is more sensitive to the initial cluster configuration than the
elliptic flow. Nuclear reaction at Fermi energy can be taken a useful way to
study cluster configuration in light nuclei.
