  The pseudogap (PG) state and its related intra-unit-cell symmetry breaking
remain the focus in the research of cuprate superconductors. Although the
nematicity has been studied in Bi$_2$Sr$_2$CaCu$_2$O$_{8+\delta}$, especially
underdoped samples, its behavior in other cuprates and different doping regions
is still unclear. Here we apply a scanning tunneling microscope to explore an
overdoped (Bi, Pb)$_2$Sr$_2$CuO$_{6+\delta}$ with a large Fermi surface (FS).
The establishment of a nematic order and its real-space distribution is
visualized as the energy scale approaches the PG.
