  The dominance of $h\to \eta \eta$ decay mode for the intermediate mass Higgs
boson is highly motivated to solve the little hierarchy problem and to ease the
tension with the precision data. However, the discovery modes for $m_h \alt
150$ GeV, $h \to \gamma\gamma$ and $W/Z h \to (\ell\nu/\ell \bar \ell) (b\bar
b)$, will be substantially affected. In this Letter, we show that $h \to \eta
\eta \to 4b$ is complementary and we can use this decay mode to detect the
intermediate Higgs boson at the LHC, via $Wh$ and $Zh$ production. Requiring at
least one charged lepton and 4 $B$-tags in the final state, we can identify a
clean Higgs boson signal for $m_h \alt 150$ GeV with a high significance and
with a full Higgs mass reconstruction. We use the next-to-minimal
supersymmetric standard model and the simplest little Higgs model for
illustration.
